The MUSIC command is in the form, MUSIC (X, Y, Z), where X, Y and Z are numeric expressions. X determines the music note and can vary from 1,2 ... to 7. Thus

  1. DO
  2. RAY
  3. MI
  4. FA
  5. SO
  6. LA
  7. TI

Y determines the Octave and can vary from 1, 2, ... to 8 with 8 being the octave with the highest upper frequency.

Z determines the amplitude and can vary from 0, 1, to 15 with 15 being the loudest.

Now, try

MUSIC (1, 1, 1)

followed by pressing CR to get a weak "DO" over the lowest octave.

Try

MUSIC (1, 1,2)

and note the increase in volume.

Try

MUSIC (2, 1,2)

and note the change to a "RAY".

Try

MUSIC (2,2,2)

and note the change to a higher octave.

Notice that once a music command is issued, the note will continue until it is replaced by another music command. To turn-off the music note, type

MUSIC (0,0,0)

Of course, always remember to terminate a command by pressing CR.
