'''25/1''', the '''25th harmonic''', is the [[harmonic]] past [[24/1]] and before [[26/1]]. It is about four [[octave]]s and eight [[semitone]]s in size. Used in harmony, it sounds particularly wide: if the base note is F1, the higher note will be about C#6. That is for all practical purposes beyond the range of {{w|choral music}}. However, it can be approached as a stack of two [[5/1]]'s, making [[chord]]s like 1-5-25. | '''25/1''', the '''25th harmonic''', is the [[harmonic]] past [[24/1]] and before [[26/1]].
