	A '''superfourth''' or '''semi-augmented fourth''' is an [[interval]] that spans three steps of the [[5L 2s\|diatonic]] scale with a quality between augmented and perfect. It exists in [[neutralization\|neutralized]] diatonic scales as exactly one half of a [[major seventh]].		A '''superfourth, ultrafourth''' or '''semi-augmented fourth''' is an [[interval]] that spans three steps of the [[5L 2s\|diatonic]] scale with a quality between augmented and perfect. It exists in [[neutralization\|neutralized]] diatonic scales as exactly one half of a [[major seventh]].

	In [[just intonation]], an interval may be classified as a superfourth if it is reasonably mapped to [[7edo\|3\7]] and [[24edo\|11\24]] (precisely three steps of the diatonic scale and five and a half steps of the chromatic scale).		In [[just intonation]], an interval may be classified as a superfourth if it is reasonably mapped to [[7edo\|3\7]] and [[24edo\|11\24]] (precisely three steps of the diatonic scale and five and a half steps of the chromatic scale).
