| Name = 30th harmonic
}}
'''30/1''', the '''30th harmonic''', is the [[harmonic]] past [[29/1]] and before [[31/1]]. It is about four [[2/1|octaves]] and eleven [[semitone (interval size measure)|semitones]] in size. Used in harmony, it sounds particularly wide: if the base note is F1, the higher note will be about E6. That is for all practical purposes beyond the range of {{w|choral music}}. However, it remains useful in some instrumental solos and ensembles. 30 is a [[largely composite number]], so this harmonic can be approached in various ways of stacking, such as 1–2–3–5–6–10–15–30, on which [[harmonic limit|higher-limit]] intervals can be added to enrich its colors.
