The symbols used to specify notes within each range are
as
follows:
CDEFGAB#R
The relationship between the 8-note scale (do, re, mi, fa, so, la, ti,
do)
and these
symbols are
as
shown below. The sharp symbol
(#)
is
used to specify
half
notes
.
Silent intervals are specified with
"R".

Duration specification
The duration specification determines the length
of
the specified note. The dura-
tions from 1/32
to
whole are specified
as
numbers from 0 to 9. (When R
is
specified,
this determines the length
of
the
silent interval.)

When sucessive notes have the same duration, the duration specification can be
omitted
for the second and following notes.
If
no
duration is specified for the first
note,
1/4 notes are assumed.
Sound volume
The volume
of
·sound produced cannot be controlled
by
the program,
but
can be
adjusted with the computer's external volume control.
Let's
·try assigning a string to SR$
to
play the theme from the beginning
of
Beethoven's Serenade in D major (Opus 25).
