Some Music Theory
Just enough.
KISS
• We will say in the key of C no flats or sharps unless indicated.
• For our purpose we will stick to 4/4 time
• If a child chooses music that is not in the key of C have them label all the flats or sharps on the music before beginning.

Notes are labeled A,B,C,D,E,F,G and refer to a part of a musical instrument. From A to A is an octave. Middle C on the piano is the center key. From C to C is an Octave. G to G etc.

Octave
An Octave is eight white keys or twelve keys in all. Do you see Fibonacci? Listen to an octave.

Each Space and line gets a letter
Sharps # and Flats b are the black keys. # black key above
b black key below A# is the same key as Bb
Tempo
Tempo is the length that a quarter note is played. Tempo 60 would play a quarter note for 1 sec. The default is 120- a quarter note for 1/2 sec.

Play [list]
• I(#) indicates instrument. Default is piano. Ex I0
• T(#) Tempo. Default 120. Ex T120
• Format for a note (duration)(letter)(#orb)(octave) Defaults 4. 4C4 is the same as C.
• R - resets all to defaults.• O# raises all following
notes one octave. Ob lowers an octave.
• L# resets note default for duration. L8 would make C same as 8C.
• + like sustain pedal stops with P or R. If you do not stop this it may not stop.
PLAY [2A#3 2P Ob Ab]sounds an A-sharp half note below middle c, pauses for the duration of a half note, lowers all following
notes by one octave, and sounds an A-flat quarter • PLAY causes the computer's synthesizer to play musical notes as
specified by its input list. Musical Notes: A B C D E F G P (for pause or a rest). R resets all to default values. It is not rest.
• Note prefixes: An integer immediately preceding a note determines its duration. 1 is a whole note, 2 is a half note, 4 is a quarter note, 8 is an eighth note, etc.
• Note suffixes: # following a note indicates it is a sharp note, b following a note indicates it is a flat note; . following a note extends its duration to 3/2 time
• Octaves: O followed by an integer between 0 and 6 sets the octave which is preset to 4. O# raises one octave, Ob lowers an octave
• (duration of the note) (note- ABCDEFGP)(#, b)(octave)
Instruments: I followed by an instrument number selects a
specific instrument for a channel.Piano Chromatic Percussion Organ
