NOTE_B0NOTE_C1NOTE_CS1NOTE_D1NOTE_DS1NOTE_E1NOTE_F1NOTE_FS1NOTE_G1NOTE_GS1NOTE_A1NOTE_AS1NOTE_B1NOTE_C2…

The first letter (A, B, C, etc.) defines the note, the optional S denotes if the note is sharp and the number defines the octave
Note
Note is a type that includes a pitch and a duration, used for a tune played by the CrcDuino. Note::END indicates the end of the tune.
Make sure to add Note::END at the end of your pattern, else very weird tune will be played.
Use it as such:
// Define a tune. Notice the Note::END at the end.
const Note TUNE_METRO[]
= { { 500, NOTE_FS4 }, { 500, NOTE_B4 }, { 800, NOTE_FS5 }, Note::END };
