A '''subfifth, infrafifth''' or '''semidiminished fifth''' is an [[interval]] that spans four steps of the [[5L 2s|diatonic]] scale with a quality between diminished and perfect. It exists in [[neutralization|neutralized]] diatonic scales as exactly one half of a minor ninth. | A '''subfifth''', '''infrafifth''' or '''semidiminished fifth''' is an [[interval]] that spans four steps of the [[5L 2s|diatonic]] scale with a quality between diminished and perfect.

In [[just intonation]], an interval may be classified as a subfifth if it is reasonably mapped to [[7edo|4\7]] and [[24edo|13\24]] (precisely four steps of the diatonic scale and six and a half steps of the chromatic scale). | In [[just intonation]], an interval may be classified as a subfifth if it is reasonably mapped to [[7edo|4\7]] and [[24edo|13\24]] (precisely four steps of the diatonic scale and six and a half steps of the chromatic scale). | ||
