    \nSay for an example you wanted to play a 'e4' you would type it like how I just did
    \nor if you wanted to play an 'es4' you would typpe it like that,
    \nthen you would put in for how long to want to play it. Just a heads up
    \na quarter note would be 1 beat, a dotted half note would be 3 beats, an eighth note
    \nwould be 0.5 beats and so on and so forth. Due to the limitations of the buzzer
    \nyou can only input from c4 to c6.""")
