Code Erklärung
CL = [0, 131, 147, 165, 175, 196, 211, 248]
CM = [0, 262, 294, 330, 350, 393, 441, 495]
major
CH = [0, 525, 589, 661, 700, 786, 882, 990]
Dies sind die Frequenzen jeder Note. Die erste 0 ist das Überspringen von CL[0], so dass die Nummer 1-7 dem
CDEFGAB des Tons entspricht.
song_1 = [ CM[3], CM[5], CM[6], CM[3], CM[2], CM[3], CM[5], CM[6],
CH[1], CM[6], CM[5], CM[1], CM[3], CM[2], CM[2], CM[3],
CM[5], CM[2], CM[3], CM[3], CL[6], CL[6], CL[6], CM[1],
CM[2], CM[3], CM[2], CL[7], CL[6], CM[1], CL[5] ]
Diese Arrays sind die Noten eines Gelieds.
