Functions

play_note(note, dur)
Plays a single specific note.
play_chord(root, type, dur, oct)
Plays a full chord.
arpeggiate(root, type, dur, times, oct)
Plays chord notes sequentially.
random_gen(root, type, dur, count, oct)
Random notes from scale.
rest(dur)
Adds silence.
get_scale(root, type, oct)
Returns an Array of notes (e.g., ['C4', 'E4', 'G4']).
map_to_scale(value, scaleArray)
Snaps a decimal (0.0 to 1.0) into a perfect musical note! Perfect for math equations.

Parameters & Objects

note: 'E5', 'C#4', etc.
root: 'C', 'C#', 'D', 'Eb', 'E', etc.
type: 'major', 'minor', 'minor7', 'major7', 'diminished', 'pentatonic', 'blues'
dur: '1n' (whole), '2n' (half), '4n' (quarter), '8n', '16n'
brain: Access to the Brain.js Neural Network library. Use new brain.NeuralNetwork().
