25/1, the 25th harmonic, is the harmonic past 24/1 and before 26/1. It is about four octaves and eight semitones 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 choral music. However, it can be approached as a stack of two 5/1's, making chords like 1-5-25.
