C in Solfeto
C is in every learner's first set, with F♯. The two are 6 semitones apart, as far as two notes can be, so the first right answers come from the notes and not from luck.
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 C with B or C♯ is the most common mistake in naming it. One semitone is the smallest step between two notes, and the one training spends longest on.
