E7 on the staff and the piano
On the treble clef, E7 sits above the sixth ledger line above the staff.
Notes this far above the staff are usually printed an octave lower with an 8va sign, so players do not have to count 6 ledger lines.
On the piano, E7 is key 80 of 88, octave 7 - a white key. It is 40 semitones above middle C (C4, key 40).

E7 at a glance
All values assume twelve-tone equal temperament at the international standard pitch of A4 = 440 Hz. In that system every semitone has the same size - a frequency ratio of 2^(1/12) - so E7 is exactly 440 × 2^(31/12) Hz. Under alternative references the note shifts with the reference: at A4 = 432 Hz, E7 becomes 2589.1 Hz.

| E6 | 1318.5 Hz | 88 | 68 |

Each octave doubles the frequency - the simplest relationship in music, and the reason notes an octave apart sound like “the same note, higher”.
