intro to basic music theory π§΅
there are 12 evenly spaced notes in western music. A through G, each has a sharp except for B and E
(a C# is the same as a D flat)
the 13th note is just the first note again but an octave higher (an integer multiple of the frequency of note 1) https://t.co/fkCBn9D4tX
