Sharps (#) and flats (b) have no effect in 7edo, because the apotome ([[2187/2048]]) is [[tempered out]]. Therefore, 7edo can be notated on a five-line staff without accidentals.  Alternatively, a seven-line stave can be used, with each horizontal line representing one pitch level. There is no distinction between major or minor, so every interval has the [[interval quality]] "perfect" instead.
