How to indicate orchestral parts/arrangement?

I noticed that people use an indication on who plays in a given piece, by using numbers and slashes to indicate the number of each type of string and wind instrument. ie Orchestra 1/1/2/4 8/8/4/4/2 (I just made that up... but you get the idea)

How EXACTLY does that indication work? I would like to be able to use it

thanks

  • The clearest method is the David Daniels 4/ OLIS system and should be used by all music publishers.

    INSTRUMENTATION FORMULA in score order.

    The formulaic arrangement of wind instruments is used here: flute, oboe, clarinet, bassoon-horn, trumpet, trombone, tuba. Amplifications, if any, are spelled out in brackets. A dot (.) separates one player from another; a slash (/) indicates doubling. Thus:

    First the Woodwinds:

    3[1.2.3/pic] 2[1.Eh] 3[1.2.3/Ebcl/bcl] 3[1.2/cbn.cbn] —

    . . . should be understood as:

    3 flutists, the 3rd player doubling on piccolo.

    2 oboists, the 2nd playing English horn throughout.

    3 clarinetists, the 3rd doubling also on E-flat clarinet and bass clarinet.

    3 bassoonists, the 2nd doubling on contrabassoon, and the 3rd playing contra throughout.

    Then the Brass, Percussion and Strings:

    4 3 3[1.2.btbn] 1 — tmp+3 — 2hp — pf — str.

    ... should be understood as:

    4 horns,

    3 trumpets.

    3 trombones, 1st and 2nd player on tenor trombone, the 3rd on bass trombone.

    1 tuba

    1 timpani player playing as many "kettles" as needed.

    3 percussion players playing as many instruments as needed. Those percussion instruments are listed separately.

    2 harps

    1 piano

    full string section.

    Any questions?

    The orchestra you give would have:

    1 flute, 1 oboe, 2 clarinets, 4 bassoons — 8 "French" horns, 8 trumpets, 4 trombones, 4 euphoniums (which would be rare in an orchestra), 2 tubas. ☺

  • you go to school as a music major years, to learn that

    you almost have to learn how to play each instrument

    you need to at least have a deep understanding to each instrument

    if you are write or compose for it
