# I must voice a cue and do not know the playable range or notation of an orchestral instrument: what do the public-domain treatises give me, and what do the digitised texts fail to give me?

Partially verified: the curator re-read none of the cited sources; S2, S1 rest on the producer's pinned reading. Forsyth (1914) opens with a reference list of every orchestral instrument's compass in actual sounding pitch plus a 'square note' that shows transposition, and then gives per-instrument written ranges in the body; Berlioz (Clarke/Bennett English text) states compasses per instrument in prose and music examples. In the OCR text that an agent can fetch, the staff-notation compasses are lost, so only compasses stated in words survive; the ranges themselves must be read from the page scans or another machine-readable source. Both treatises treat range as one input to character and balance, not as the whole answer.
