Two-character alphabetic codes that identify the form of musical composition. Enter the specific multiple MARC Composition Codes or any non-MARC codes in field 047 when you use the code mu in Comp. Determine forms of composition from subject access points, genre/form terms, titles, preferred titles, or contents. You must decide the extent of the coverage.

You may also use field 380 to record form of musical composition information in textual form.


If you choose to use codes from the MARC Form of Musical Composition Code List, those codes are reproduced below for convenience.

Do not use MARC Codes mu, nn, uu, and zz in field 047. When the code mu appears in Comp, field 047 should be used in either or both of the following ways:

  • MARC Composition Codes: Give each appropriate MARC Composition Code in a separate subfield ǂa.
  • Non-MARC codes: Give each appropriate non-MARC musical form code in a separate subfield ǂa and provide the source code in ǂ2.

Do not mix codes from different sources in the same 047 field.

When appropriate, you may assign a specific MARC Composition Code in Comp and a non-MARC code or codes in field 047.

For additional code lists that may be used in field 047, see Musical Composition Form Code Source Codes.

MARC musical composition code. The source of the code is the MARC Form of Musical Composition Code List.

ǂa Form of musical composition code

Enter each code in a separate subfield ǂa. Codes are recorded in order of importance to the item being described. The code for the most important form of composition is given first.


If the item has both an oratorio and a cantata, enter:

Comp:     mu
047     or ǂa ct

If the item has both blues and jazz, enter:

Comp:     mu
047     bl ǂa jz
ǂ2 Source of code

The source of the musical composition code. See Musical Composition Form Code Source Codes.

When using codes from the MARC Form of Musical Composition Code List, prefer the use of code blank in the 2nd indicator position rather than 2nd indicator code 7 in combination with subfield ǂ2 containing code marcmuscomp.

Use code iamlmf to indicate a code from the list of Musical Forms codes maintained by the International Association of Music Libraries.

Comp:     rc
047   7 rgg ǂ2 iamlmf

The resource contains a humoresque:

Comp:     mu
047   7 hum ǂ2 iamlmf
[The IAML code for humoresque is hum, for which there is no appropriate specific MARC Composition Code]
