Decoding music onto transparent film - uses two colour system using vertical synchronising marks with interconnecting curved and straight lines

摘要

The method of decoding musical texts on a transparent film or on the music itself uses signs in first and second colours of the decoding code of a piece of music to place on the music printing. The two colour signs are to synchronise notes. A vertical trace (2) gives the first synchronising mark for a note assembly and one in another colour denotes the end of the assembly. There are circular synchronising marks above a vertical trace of the same colour and straight and curved traces (1) in a second one.
