General description

MUSICMASTER enables you to create your own tunes in two
modes:
- by using the Spectrum keyboard to simulate a piano keyboard;
  we supply a keyboard overlay to help you. [see MUSICMAS.GIF]
- by entering the notes by name.
You can then listen to your tune, change it, add to it, and save it.
You can reload any tune you have saved, and work on it again.

When you create or amend a tune, the notes are both sounded and
displayed on the screen.


Operating instructions

Connect your ZX Spectrum as shown in the diagram.
Load the program with the command
	LOAD""
Start your cassette player and then press the ENTER key on your
Spectrum. MUSICMASTER will load in four parts, and tell you when
to switch off your tape recorder. It will then be ready to run.
If you stop the program and later want to start it again without
reloading, give the command GOTO 1. In no circumstances use the
commands RUN or CLEAR; they will erase the program from memory.

As you load your program you will see the five lines of the musical
stave appear on the screen. The sign on the left is the treble clef
which shows that the note on the stave would normally be played
with the right hand on the piano keyboard. The stave can be
extended on the left with little lines called leger lines, so that notes
which fall outside it can be marked.

The note lowest in pitch is at the left of this stave, and the highest is
at the right. The gap or interval between a and A, b and B, c and C is
called an octave.

The notes on this stave have solid heads and vertical tails which
may point either up or down - they are called crotchets. The form of
a note indicates its duration - the time for which it sounds relative to
the other notes in the tune. MUSICMASTER will tell you all about this.


Stave or keyboard mode

When you have loaded the program, you can then select either
STAVE mode or KEYBOARD mode by pressing 1 or 2.

- STAVE mode gives you a range of two octaves upwards from
  A below middle C. You enter notes by pressing the note name
  (a to g for the lower octave and A to G for the upper octave),
  prefaced by S for sharp, L for flat or N for natural.

- KEYBOARD mode allows the top two rows of your Spectrum
  keyboard to simulate a keyboard instrument with 10 white notes
  and 7 black notes from middle C upwards. Fasten the overlay to
  your Spectrum keyboard to help you play.

In either case the following commands are then available:

1 Notes on music
If you select this option, you will then be offered a number of
demonstrations as follows:
	1 Note pitch
	2 Note duration
	3 Rests
	4 Key signature
	5 Time signature
	6 Return to main menu

2 Create a tune
If you want to write a tune, you must first tell the computer whether
you want to include flats or sharps in the key signature and what
time signature you want. Then you can enter your tune.

Note that in KEYBOARD mode your Spectrum will automatically
adjust the 'sign' of the note to the key signature.

The screen will remind you which keys tell the computer:

- that the next note is to be flat/sharp/natural to override the key
  signature for this note (STAVE mode only),
- the note itself,
- to insert a rest,
- to delete the last note displayed. If no notes are left on the
  screen after the deletion, the previous three notes are
  redisplayed,
- that the value of the next note (its length or duration) is to be
  shorter or longer than the last note. At the start of your tune, the
  note value is that of the time signature (eg. crotchet for common
  time). Changing this to, say, a minim causes all future notes
  to be minims until the next change,
- to copy your TV screen display to your ZX Printer
  (if connected),
- to end your tune.

3 Play a tune
Your Spectrum will play your tune back at your chosen speed. If at
any time you want to make changes to it, or if you want to add notes
to the end of the tune, the computer will respond by displaying the
last three notes it has played and you will automatically be taken to
the "Amend a tune" function, described next.

4 Amend a tune
You select this facility either by pressing 4 when the main menu is
displayed, or by indicating that you want to amend your tune while
you are listening to it (see above).

Both the key and time signatures are retained, but you may alter
notes in your tune at will. All the facilities of "Create a tune" are
available to you, as well as the possibilities of:

- tabbing through the original tune, copying notes to your new tune,
- exiting, erasing any part of the original tune not yet referred to,
- exiting, copying any remaining notes in the old tune across to
  the new tune.

5 Save a tune
Use this to record your tune on to cassette tape; follow the
instructions in your Spectrum handbook.

Note that this records the data needed by your Spectrum to play
your tune. Listening to the tape directly will not be particularly
tuneful!

6 Load a tune
This loads any tune you have previously saved using MUSICMASTER.

7 Stop
Exit from program.

8 Switch to keyboard/stave mode
This enables you to switch between STAVE mode and KEYBOARD
mode whenever you wish.


Additional hints

Only one tune is retained in the computer at any time. If you enter
mode 2 (Create a tune) or mode 6 (Load a tune), then any existing
tune not already Saved (mode 5) is lost.

Each tune has a limit of 1000 notes. A single note, which may be
displayed as several notes if it spans a bar-line, counts as one note.

Request for the next note to be sharp, flat or natural (other than
when you are initially specifying the key signature) apply to the next
note only, and not to the remainder of the bar.

Requests for double sharps or flats are simply treated as single
sharps or flats.
