What is E6?
E6 is the E in octave 6 — the 68th key of the 88 on a full-size piano, counted from the bottom. In standard tuning it sounds at 1318.51 Hz. It sits 28 half-steps above middle C (C4).
To find it, locate any group of two black keys: the white key just to their left is a C. Count up from middle C (C4) 2 octaves to reach octave 6, then step to E.
Every octave doubles the frequency: the E one octave up sounds at 2637.02 Hz and the one below at 659.26 Hz. The same piano key can be written as E, Fb, D## depending on the musical context — same sound, different spelling.
