D in Solfeto
D joins 11th, after C, F♯, A, D♯, E, G♯, G, C♯, B and F. Its nearest neighbour already in the set is D♯, 1 semitone away. From here on every new pitch sits a semitone from one already learned, which is the hardest kind of pair to tell apart.
It joins when the set before it is held: right 90 percent of the time, quickly, with no pitch left behind. The method is in how to train absolute pitch.
The notes beside it
Mixing up D with C♯ or D♯ is the most common mistake in naming it. One semitone is the smallest step between two notes, and the one training spends longest on.
