The 11 of A is D
The 11 (eleven) of A is D: a perfect eleventh above the root.
A — the root, 1D — the 11
How to find it
An 11th is a 4th an octave up, so it takes the 4th's letter: A, B, C, D.
Then the sound: a perfect eleventh is 17 semitones above A, which is exactly where D is — no sharp or flat needed.
Where you meet it
The 11 is the 4 an octave up. It sits naturally on minor chords; on a major chord it clashes with the 3rd, which is why the ♯11 exists.
