Note names: C-D-E ↔ do-re-mi, and accidentals

The note names both ways: the seven notes by letter and by syllable (dó ré mi, as Portuguese spells them), the C major scale named both ways, the accidentals and their names, the twelve sounds of the octave in both spellings, and the two ways of numbering the octaves, where middle C is C4 in English and dó3 in Brazilian theory books.
