This should be done on either vellum or opaque paper and clearly reproduced, back to back. All instructions should be in a conventional language such as English, Italian, German, or French. There should be a page at the beginning of the work which lists the full instrumentation required, including doublings, keys of transposing instruments, and all percussion instruments. An indication of how many percussionists will be required is helpful, though each orchestra may or may not adhere to that number. Any special staging should also be mentioned on this, or a subsequent page.
Detailed diagrams are helpful especially for complex staging.
If there are deviations from standard musical notation, an explanation should appear next to the instrumentation page. There should be an approximate duration for each movement and a total duration included on the instrumentation page. All tempo indications should appear above the first line and above the first violin line on each score page. Placement of measure numbers should be the same throughout the work, i.e. above, below, or on a special line of the grand staff such as above the first violins. If rehearsal letters are to be used, they must be used in conjunction with measure numbers.
