In piano system, notes are denotes by alphabets A to G. Also '#' is used to denote sharp and 'b' is used to denote flats as usual. A single digit following note is used to denote octave and number followed that is used to denote note length Examples of note
A316 # denotes a full A note in 3rd octave
D#28 # denotes half D sharp note in second octave
Eb54 # denotes a quater E flat note in 5 octave
Sequences are used to denote notes one after the other. Sequence are denoted by enclosing series of notes between square brackets Example of note sequences
[ A34 D#34 Eb48 ]
Above sequence will play the notes one after the other
Blocks are used to denote notes which are played simultaneously. Blocks are denoted by enclosing series of notes between curly braces Blocks can be used to denote cords Example of note blocks
{ C34 E34 G34 }
Above block will play as C major chord
Variables allow one to give name to musical sequences. These names can then be used in other musical sequences For examples
cmajor+={C34 E34 G34}
main+=[
cmajor cmajor cmajor
]
Above program defines cmajor and then uses it in main sequence thrice. This should play cmajor cord thrice
Sequence and blocks can be arbitrarily nested within each other. Such that one can define different clefs and can have chords or notes being played within each clef
