Coding A Song From Sheet Music - Commodore 128 System Manual

CODING A SONG FROM SHEET MUSIC

This section provides a sample piece of sheet music and
illustrates how to decode notes from a musical staff and translate
them into a form the Commodore 128 can understand. This
exercise is substantially faster and easier if you know how to read
music. However, you don't have to be a musician to be able to
play the tune on your Commodore 128. For those of you who
cannot read music, Figure 7-11 shows how a typical musical staff
is arranged and how the notes on the staff are related to the keys
on a piano.
Figure 7-12 is an excerpt from a composition titled Invention 13
(Inventio 13 in Italian), by Johann Sebastian Bach. Although this
composition was written a few hundred years ago, it can be
played and enjoyed on the most modern of computer
synthesizers, such as the SID chip, in the Commodore 128. Here
are the opening measures of Invention 13.
