Introduction
Have you ever had a tune running around in your head that you wanted to write
down, but you didn't know anything about music? Now, using the TRS - 80
Color Computer Music program, you can not only write melody lines, but
harmony as well.
Composing your own music will become easier with practice_ You can experi-
ment with timing, key signatures and tone .. All compositions can be saved on
tape for tutu re playing.
As you read the manual, you may see some unfamiliar terms. Th ere is a glossary
in the back, defining these terms.
Setting Up
First, make sure the cassette is properly connected to the computer. Turn on the
TV and turn up the volume slightly. Insert the Music cartridge in the slot on the
right side of the computer. Next, when you turn on the computer, the bass and
treble clef staves will appear.
Setting theVoice
We wil I begin by setting the voice. The voice produces different tone qualities
(or timbres), and is set by pressing three keys.

1. Press[SZ]. This tells the computer that you are setting the voice. The first
number you enter will determine the voice of the top note. The second
number sets the voice of the bottom note. You may choose from the
following numbers.
0 - No Sound
1 - Norma l smooth sound
2 - Loud smooth sound
3 - Normal harsh sound
4 - Loud harsh sound
2. Press [I] to set the voice of the top note.
3. Press [ID to set the voice of the bottom note . The "0" silences the bottom
notes so that you will be able to concentrate on the melody.
Changingthe Voice
The voice may be changed anywhere within the compos1t1on by pressing~,
then the numbers for the tones you want. For example, by pressing the [2] or@
keys for both the top and bottom notes, you can make a part of your composi-
tion forte, or accent a single note. An accent is achieved by inserting a loud,
harsh voice with in the score directly before the note you want to accent. After
the accented note, insert a normal smooth voice.
Now press the 8 key to advance the score to the next space. You must press the
2

El after entering each command.
Let's begin by composing the melody, "Over the Rainbow". When we are
finished
with the melody, we will add more detail and harmony to the tune.
After this tune, you may want to try another score at the end of the manual,
and soon you will be composing your own music.
Entering a Score
This is how you write music on a TRS-80 Color Computer:
1. To begin, press the rnJ key to set a repeat bar at the beginning of the score
and press B
to advance to the next space.
2. Press the slash, [ZL key. At the bottom center of the screen, you will see
that the "tail" of the arrow has moved to the right. This will give you
control of the notes on the bottom staff. Beneath the "tail", the name of
the current item is shown.
3. Press ITJ or [J]. A quarter note will appear midway between the two staves.
This
is Middle C.
4. Press [J) and a second note will appear below the first. Continue to press
(!]until the note is at the bottom of the bass clef. This will keep the
bottom note out of your way while you are composing the melody on the
treble clef.
3

5. Press the 0 key again to return your control to the top note. The "tail"
will move back to the left, with the current item on the left.
Inserting and Linking Notes
1. The first note we need for "Over the Rainbow", is a half note at Middle
C. (We will designate this note as M-C in the rest of the manual.) Since the
note is already at M -C , simply press [l] to make it a half note. At the
bottom of your screen, you will see the letter C which indicates that the
current item is the note, C. Press the El key to move the score on to the
next space.
2. Press the [JJ and a secor1d note will appear at M-C. Press the [JJ again until
the note moves up to the next C on the staff. Press ~ to make this C a
quarter note .
3. Link,
or slur this note to the note that follows by pressing the [(J key. A
small
dot will appear beside the note to indicate that the notes are to be
connected. Press the El to move to the next space.
4. Press the [I] aga in to enter another C. Press[) to slur this note. Remember
to press the El after you enter each note .
Add the following notes to the score in the same manner. Letters in quotes are
command keys and not notes. Each note will have the same value as the previous
note unless you change it. An up or down arrow preceding each note will tell
4

you the direction to move.
If you forget to enter the note time before pressing the EL you can return to the
note that needs correction by pressing the 8 key.
tB"4", tG"B", tA, tB"4", tC, C"L", tM-C"L", tA"L", A"L", {-G"L", G"L",
G"L", G"L", "RR4"
Inserting Rests
Pressing the letter [BJ will insert a rest. The first time it is pressed a note appears.
Pressing
[BJ again will make the rest appear on the clef on which you are
working. The time of each rest can be changed in the same way note times are
changed. Press
[ID for a whole rest, ~ for a half-rest, @] for a quarter-rest, !ID
for an eighth-rest, and [ID for a sixteenth -rest.
If you inserted all the notes correctly the score will look like this:
