MuniYield Quality Fund, Inc.

The Benefits and Risks of Leveraging

MuniYield Quality Fund, Inc. utilizes leveraging to seek to enhance the yield
and net asset value of its Common Stock. However, these objectives cannot be
achieved in all interest rate environments. To leverage, the Fund issues
Preferred Stock, which pays dividends at prevailing short-term interest rates,
and invests the proceeds in long-term municipal bonds. The interest earned on
these investments, net of dividends to Preferred Stock, is paid to Common Stock
shareholders in the form of dividends, and the value of these portfolio holdings
is reflected in the per share net asset value of the Fund's Common Stock.
However, in order to benefit Common Stock shareholders, the yield curve must be
positively sloped; that is, short-term interest rates must be lower than
long-term interest rates. At the same time, a period of generally declining
interest rates will benefit Common Stock shareholders. If either of these
conditions change, then the risks of leveraging will begin to outweigh the
benefits.

To illustrate these concepts, assume a fund's Common Stock capitalization of
$100 million and the issuance of Preferred Stock for an additional $50 million,
creating a total value of $150 million available for investment in long-term
municipal bonds. If prevailing short-term interest rates are approximately 3%
and long-term interest rates are approximately 6%, the yield curve has a
strongly positive slope. The fund pays dividends on the $50 million of Preferred
Stock based on the lower short-term interest rates. At the same time, the fund's
total portfolio of $150 million earns the income based on long-term interest
rates. Of course, increases in short-term interest rates would reduce (and even
eliminate) the dividends on the Common Stock.

In this case, the dividends paid to Preferred Stock shareholders are
significantly lower than the income earned on the fund's long-term investments,
and therefore the Common Stock shareholders are the beneficiaries of the
incremental yield. However, if short-term interest rates rise, narrowing the
differential between short-term and long-term interest rates, the incremental
yield pickup on the Common Stock will be reduced or eliminated completely. At
the same time, the market value of the fund's Common Stock (that is, its price
as listed on the New York Stock Exchange) may, as a result, decline.
Furthermore, if long-term interest rates rise, the Common Stock's net asset
value will reflect the full decline in the price of the portfolio's investments,
since the value of the fund's Preferred Stock does not fluctuate. In addition to
the decline in net asset value, the market value of the fund's Common Stock may
also decline.

As a part of its investment strategy, the Fund may invest in certain securities
whose potential income return is inversely related to changes in a floating
interest rate ("inverse floaters"). In general, income on inverse floaters will
decrease when short-term interest rates increase and increase when short-term
interest rates decrease. Investments in inverse floaters may be characterized as
derivative securities and may subject the Fund to the risks of reduced or
eliminated interest payments and losses of invested principal. In addition,
inverse floaters have the effect of providing investment leverage and, as a
result, the market value of such securities will generally be more volatile than
that of fixed-rate, tax-exempt securities. To the extent the Fund invests in
inverse floaters, the market value of the Fund's portfolio and the net asset
value of the Fund's shares may also be more volatile than if the Fund did not
invest in these securities. As of April 30, 2004, the percentage of the Fund's
total net assets invested in inverse floaters was 11.51%.

Swap Agreements

The Fund may also invest in swap agreements, which are over-the-counter
contracts in which one party agrees to make periodic payments based on the
change in market value of a specified bond, basket of bonds, or index in return
for periodic payments based on a fixed or variable interest rate or the change
in market value of a different bond, basket of bonds or index. Swap agreements
may be used to obtain exposure to a bond or market without owning or taking
physical custody of securities.

A Letter From the President

Dear Shareholder

For the six-month and 12-month periods ended April 30, 2004, the Lehman Brothers
Municipal Bond Index posted returns of +1.19% and +2.68%, respectively. Its
taxable counterpart, the Lehman Brothers Aggregate Bond Index, had returns of
+1.25% and +1.82% for the same periods. Amid considerable month-to-month
volatility, tax-exempt bond yields rose over the past year, although not to the
same extent as 10-year U.S. Treasury yields. In all, tax-exempt securities
continued to be an attractive fixed income investment alternative.

As of April month-end, the Federal Reserve Board maintained its accommodative
policy stance, although a better-than-expected employment report for the month
of March prompted speculation that an interest rate increase could come sooner
than many had expected. On April 2, 2004, the good news on the employment front
-- previously the one dim spot in an otherwise bright economic picture -- helped
prompt the yield on the 10-year Treasury bond to spike nearly 25 basis points
(.25%) from 3.91% to 4.15%. Market watchers continue to monitor the economic
data and Federal Reserve Board language for indications of interest rate
direction. If economic growth maintains its recent pace and employment figures
continue to improve, many believe it is just a matter of time before interest
rates move upward.

Equity markets, in the meantime, gleaned support from the improving economic
environment and provided attractive returns. For the six-month and 12-month
periods ended April 30, 2004, the Standard & Poor's 500 Index returned +6.27%
and +22.88%, respectively. Significant fiscal and monetary stimulus in 2003,
including low interest rates and tax cuts, has opened the door to consumer
spending, capital spending, increases in exports and long-awaited job growth. As
expected, these developments have led the way to improvements in corporate
earnings -- a positive for stock markets.

The events and efforts of the past year leave us with a much stronger economy
today. Of course, markets will always fluctuate, and there are many
uncertainties -- not the least of which are geopolitical in nature -- which can
translate into negative market movements. Keeping this in mind, we encourage you
to revisit your portfolio and your asset allocation strategy to ensure you are
well positioned to take advantage of the opportunities that lie ahead.
Importantly, your financial advisor can help you develop a strategy most
suitable for your circumstances through all types of market and economic cycles.

We thank you for trusting Merrill Lynch Investment Managers with your investment
assets, and we look forward to serving you in the months and years ahead.

                                        Sincerely,


                                        /s/ Terry K. Glenn

                                        Terry K. Glenn
                                        President and Director

A Discussion With Your Fund's Portfolio Manager

      We remained focused on enhancing yield and preserving net asset value in a
volatile interest rate environment, and the Fund was able to outperform its
comparable Lipper category average.

Describe the recent market environment relative to municipal bonds.

For much of the six-month period, a positive economic backdrop helped bond
prices to move higher as yields, which typically move opposite of prices,
declined. In early April, however, a surprisingly strong monthly employment
report triggered fears that the long-accommodative Federal Reserve Board might
raise interest rates sooner than many had expected. As a result, bond yields
rose (prices fell) sharply for the remainder of the period. At the end of April,
long-term U.S. Treasury bond yields had climbed to 5.13%, representing an
increase of approximately 15 basis points (.15%) over the past six months.
Ten-year U.S. Treasury note yields stood at 4.30% as of period-end, an increase
of more than 20 basis points.

Tax-exempt bond yields generally mimicked the movement of their taxable
counterparts, although volatility in the municipal market was more subdued.
Long-term revenue bond yields, as measured by the Bond Buyer Revenue Bond Index,
rose just four basis points over the past six months. For the same period,
yields on AAA-rated issues maturing in 30 years increased approximately 10 basis
points to 4.93% while yields on 10-year, AAA-rated issues increased more than 16
basis points to nearly 4%, according to Municipal Market Data. The more marked
increase in 10-year bond yields may be attributed to the fact that recent
issuance has been heavily concentrated in the 10-year - 20-year range. The
resulting supply imbalance prompted higher intermediate bond yields (and lower
prices). Longer-maturity and lower-rated issues continued to benefit from more
favorable supply/demand factors and, therefore, have seen less price
depreciation. For the six-month period as a whole, municipal bond supply
declined approximately 5% compared to the same period a year ago.

While investor enthusiasm for stocks has taken some attention away from fixed
income markets, overall demand for tax-exempt municipal bonds has remained
positive. Recent Federal Reserve Board statistics showed that U.S. household
holdings of municipal securities increased by more than $25 billion during the
fourth quarter of 2003 to approximately $680 billion. In addition, data from the
Investment Company Institute indicates that, in just the first three months of
2004, tax-exempt bond funds have seen net new cash flows of almost $640 million.

How did the Fund perform in light of the existing market conditions?

For the six-month period ended April 30, 2004, the Common Stock of MuniYield
Quality Fund, Inc. had net annualized yields of 6.46% and 7.30%, based on a
period-end per share net asset value of $15.08 and a per share market price of
$13.35, respectively, and $.486 per share income dividends. Over the same
period, the total investment return on the Fund's Common Stock was +1.50%, based
on a change in per share net asset value from $15.36 to $15.08, and assuming
reinvestment of $.486 per share ordinary income dividends.

For the six-month period ended April 30, 2004, the Fund's Auction Market
Preferred Stock (AMPS) had an average yield of .86% for Series A, .90% for
Series B, .97% for Series C and .93% for Series D.

The Fund's return, based on net asset value, exceeded that of its comparable
Lipper category of Insured Municipal Debt Funds (Leveraged), which had an
average return of +1.01% for the six-month period. (Funds in this Lipper
category invest primarily in municipal debt issues insured as to timely payment.
These funds can be leveraged via use of debt, preferred equity and/or reverse
repurchase agreements.) The Fund's outperformance is primarily attributed to the
prerefunding of several holdings. When municipal bonds are prerefunded, they are
essentially refinanced ahead of their maturity date. The proceeds from the
refinancing are typically used to purchase government-backed debt. This is then
pledged to pay off the original debt at an earlier call date. In short, when the
bond holdings are prerefunded, their prices generally increase sharply,
particularly when the yield curve is relatively steep. In addition, the Fund
maintained its dividend during the period at $.081 a share, generating an
above-average tax-exempt yield for the Fund's shareholders.


4             MUNIYIELD QUALITY FUND, INC.      APRIL 30, 2004


For a description of the Fund's total investment return based on a change in the
per share market value of the Fund's Common Stock (as measured by the trading
price of the Fund's shares on the New York Stock Exchange), and assuming
reinvestment of dividends, please refer to the Financial Highlights section
included in this report. As a closed-end fund, the Fund's shares may trade in
the secondary market at a premium or discount to the Fund's net asset value. As
a result, total investment returns based on changes in the market value of the
Fund's Common Stock can vary significantly from total investment return based on
changes in the Fund's net asset value.

What changes were made to the portfolio during the period?

We continued to pursue three general themes in managing the Fund. First, when
making new purchases, we tended to target longer-dated bonds, generally in the
25-year range. The municipal yield curve flattened out past this range;
therefore, there was no significant yield to be gained by extending out any
further. Second, we found it advantageous to purchase California municipal
bonds. Given recent heavy supply of California issues, we have been able to make
purchases at attractive spreads relative to national municipal bonds and
historic norms for the state. We believe these holdings should benefit Fund
performance as California's finances start to improve and state bonds begin
trading at more typical levels. Finally, when available, we continued to favor
premium-coupon bonds when making new purchases.

We generally maintained the Fund's fully invested position throughout the
period, seeking to enhance shareholder income. With short-term interest rates at
historic lows, the cost of holding cash reserves would have been relatively high
in terms of its effect on performance.

Given the historically low short-term interest rates, the Fund's borrowing costs
remained at attractive levels of around 1%. These levels, in combination with a
positively sloped yield curve, provided a generous income benefit to the Common
Stock shareholder from the leveraging of Preferred Stock. We believe the Fund's
borrowing costs should remain at relatively low levels for the foreseeable
future. While the timing is questionable, the Federal Reserve Board's next move
likely will be to raise short-term interest rates. The increase, however, is
expected to be gradual and should not have a material impact on the positive
advantage leverage has had on the Fund's Common Stock yield. However, should the
spread between short-term and long-term interest rates narrow, the benefits of
leveraging will decline and, as a result, reduce the yield on the Fund's Common
Stock. At the end of the period, the Fund's leverage amount, due to AMPS, was
30.35% of total assets. (For a more complete explanation of the benefits and
risks of leveraging, see page 2 of this report to shareholders.)

How would you characterize the Fund's position at the close of the period?

The portfolio essentially remained fully invested in high-quality municipal
bonds at the end of the period, which we believe should continue to provide a
material benefit to the Common Stock shareholder as short-term interest rates
remain near their historic lows. We maintained our defensive market stance at
the close of the period in recognition of improving economic conditions. We
believe this positioning prepares the Fund for relative outperformance once
interest rates inevitably begin to rise. Finally, we remained overweight in
premium-coupon bonds and continued to favor maturities in the 25-year range.

Notes to Financial Statements

1. Significant Accounting Policies:

MuniYield Quality Fund, Inc. (the "Fund") is registered under the Investment
Company Act of 1940, as amended, as a non-diversified, closed-end management
investment company. The Fund's financial statements are prepared in conformity
with accounting principles generally accepted in the United States of America,
which may require the use of management accruals and estimates. Actual results
may differ from these estimates. These unaudited financial statements reflect
all adjustments, which are, in the opinion of management, necessary to a fair
statement of the results for the interim period presented. All such adjustments
are of a normal, recurring nature. The Fund determines and makes available for
publication the net asset value of its Common Stock on a weekly basis. The
Fund's Common Stock is listed on the New York Stock Exchange under the symbol
MQY. The following is a summary of significant accounting policies followed by
the Fund.

(a) Valuation of investments -- Municipal bonds are traded primarily in the
over-the-counter markets and are valued at the last available bid price in the
over-the-counter market or on the basis of yield equivalents as obtained by the
Fund's pricing service from one or more dealers that make markets in the
securities. Financial futures contracts and options thereon, which are traded on
exchanges, are valued at their closing prices as of the close of such exchanges.
Options written or purchased are valued at the last sale price in the case of
exchange-traded options. In the case of options traded in the over-the-counter
market, valuation is the last asked price (options written) or the last bid
price (options purchased). Swap agreements are valued by quoted fair values
received daily by the Fund from the counterparty. Short-term investments with a
remaining maturity of sixty days or less are valued at amortized cost, which
approximates market value. Securities and assets for which market quotations are
not readily available are valued at fair value as determined in good faith by or
under the direction of the Board of Directors of the Fund, including valuations
furnished by a pricing service retained by the Fund, which may utilize a matrix
system for valuations. The procedures of the pricing service and its valuations
are reviewed by the officers of the Fund under the general supervision of the
Board of Directors.

(b) Derivative financial instruments -- The Fund may engage in various portfolio
investment strategies both to increase the return of the Fund and to hedge, or
protect, its exposure to interest rate movements and movements in the securities
markets. Losses may arise due to changes in the value of the contract or if the
counterparty does not perform under the contract.

o     Financial futures contracts -- The Fund may purchase or sell financial
      futures contracts and options on such futures contracts. Futures contracts
      are contracts for delayed delivery of securities at a specific future date
      and at a specific price or yield. Upon entering into a contract, the Fund
      deposits and maintains as collateral such initial margin as required by
      the exchange on which the transaction is effected. Pursuant to the
      contract, the Fund agrees to receive from or pay to the broker an amount
      of cash equal to the daily fluctuation in value of the contract. Such
      receipts or payments are known as variation margin and are recorded by the
      Fund as unrealized gains or losses. When the contract is closed, the Fund
      records a realized gain or loss equal to the difference between the value
      of the contract at the time it was opened and the value at the time it was
      closed.

o     Options -- The Fund may write covered call options and purchase put
      options. When the Fund writes an option, an amount equal to the premium
      received by the Fund is reflected as an asset and an equivalent liability.
      The amount of the liability is subsequently marked to market to reflect
      the current market value of the option written. When a security is
      purchased or sold through an exercise of an option, the related premium
      paid (or received) is added to (or deducted from) the basis of the
      security acquired or deducted from (or added to) the proceeds of the
      security sold. When an option expires (or the Fund enters into a closing
      transaction), the Fund realizes a gain or loss on the option to the extent
      of the premiums received or paid (or gain or loss to the extent the cost
      of the closing transaction exceeds the premium paid or received).


18            MUNIYIELD QUALITY FUND, INC.      APRIL 30, 2004


Notes to Financial Statements (continued)

      Written and purchased options are non-income producing investments.

o     Forward interest rate swaps -- The Fund may enter into forward interest
      rate swaps. In a forward interest rate swap, the Fund and the counterparty
      agree to make periodic net payments on a specified notional contract
      amount, commencing on a specified future effective date, unless terminated
      earlier. When the agreement is closed, the Fund records a realized gain or
      loss in an amount equal to the value of the agreement.

(c) Income taxes -- It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required.

(d) Security transactions and investment income -- Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Realized gains and losses on security transactions are determined on the
identified cost basis. Dividend income is recorded on the ex-dividend dates.
Interest income is recognized on the accrual basis. The Fund amortizes all
premiums and discounts on debt securities.

(e) Dividends and distributions -- Dividends from net investment income are
declared and paid monthly. Distributions of capital gains are recorded on the
ex-dividend dates.

2. Investment Advisory Agreement and Transactions with Affiliates:

The Fund has entered into an Investment Advisory Agreement with Fund Asset
Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc.
("PSI"), an indirect, wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML
& Co."), which is the limited partner.

FAM is responsible for the management of the Fund's portfolio and provides the
necessary personnel, facilities, equipment and certain other services necessary
to the operations of the Fund. For such services, the Fund pays a monthly fee at
an annual rate of .50% of the Fund's average weekly net assets, including
proceeds from the issuance of Preferred Stock. For the six months ended April
30, 2004, FAM reimbursed the Fund in the amount of $9,902.

For the six months ended April 30, 2004, the Fund reimbursed FAM $6,879 for
certain accounting services.

Certain officers and/or directors of the Fund are officers and/or directors of
FAM, PSI, and/or ML & Co.

Dividend Policy

The Fund's dividend policy is to distribute all or a portion of its net
investment income to its shareholders on a monthly basis. In order to provide
shareholders with a more stable level of dividend distributions, the Fund may at
times pay out less than the entire amount of net investment income earned in any
particular month and may at times in any month pay out such accumulated but
undistributed income in addition to net investment income earned in that month.
As a result, the dividends paid by the Fund for any particular month may be more
or less than the amount of net investment income earned by the Fund during such
month. The Fund's current accumulated but undistributed net investment income,
if any, is disclosed in the Statement of Net Assets, which comprises part of the
financial information included in this report.

MuniYield Quality Fund, Inc. seeks to provide shareholders with as high a level
of current income exempt from Federal income taxes as is consistent with its
investment policies and prudent investment management by investing primarily in
a portfolio of long-term, high-grade municipal obligations the interest on which
is exempt from Federal income taxes in the opinion of bond counsel to the
issuer.

This report, including the financial information herein, is transmitted to
shareholders of MuniYield Quality Fund, Inc. for their information. It is not a
prospectus. Past performance results shown in this report should not be
considered a representation of future performance. The Fund has leveraged its
Common Stock and intends to remain leveraged by issuing Preferred Stock to
provide the Common Stock shareholders with a potentially higher rate of return.
Leverage creates risks for Common Stock shareholders, including the likelihood
of greater volatility of net asset value and market price of shares of the
Common Stock, and the risk that fluctuations in the short-term dividend rates of
the Preferred Stock may affect the yield to Common Stock shareholders.
Statements and other information herein are as dated and are subject to change.
