{{Short description|Technical musical term}}
'''''Homotonal''''' (same-tonality) is a technical musical term that describes the [tonal](/source/tonality) structure of multi-movement [compositions](/source/musical_composition). It was introduced into [musicology](/source/musicology) by [Hans Keller](/source/Hans_Keller). According to Keller's definition and usage, a multi-movement composition is 'homotonal' if all of its [movements](/source/movement_(music)) have the same [tonic](/source/tonic_(music)) (keynote).

'Homotonality' is common in compositions of the [Baroque era](/source/Baroque_music): many Baroque multi-movement works based on dance-forms manifest the same tonic—and even the same ''mode'' (major or minor) – throughout. Thus, for example, [J.S. Bach](/source/J.S._Bach)'s solo violin partita BWV 1004 is homotonal ''[all movements in D minor]'', as is his solo flute partita BWV 1013 ''[all movements in A minor]''. Similarly, [Vivaldi](/source/Antonio_Vivaldi)'s sonata for oboe and continuo RV53 (n.d.) is homotonal ''[all movements in C minor]''. Homotonality is even encountered in some Baroque concertos: examples include Vivaldi's Cello Concertos RV401 (n.d.) ''[all movements in C minor]'' and RV416 (n.d.) ''[all movements in G minor]'', as well as the second concerto of his most famous work [The Four Seasons](/source/The_Four_Seasons_(Vivaldi)) ("Summer" RV315) (1725) ''[all movements also in G minor]'', and [Jean-Marie Leclair](/source/Jean-Marie_Leclair)'s Violin Concerto Op.7 No 1 (1737) ''[all movements in D minor]''.

With the [Classical era](/source/Classical_period_(music)), however, the situation changes. Outside of two-movement works (which, classically speaking, will maintain the same tonic for both movements and will thus be homotonal by definition), classical-era homotonality is relatively rare: a classical work in three movements will normally move to a different tonic for its middle movement, and a classical work in four movements will normally have at least one of its middle movements in a key other than the original tonic.

The classical composer most closely associated with the homotonal principle is [Joseph Haydn](/source/Joseph_Haydn). 

Keller himself was keen to emphasise that different classical composers showed differing degrees of interest in homotonal structure:

{{quote|Although [Mozart](/source/Mozart), as opposed to Haydn, tended to work within narrow tonal frameworks, he did not carry the homotonal approach very far into his maturity . . . whereas Haydn did: some of the older master's greatest string quartets adhere to a single tonality"<ref>Hans Keller, 'Wolfgang Amadeus Mozart (1756–91)', in ''The Symphony'' (Ed. Robert Simpson; London, 1966), p.58</ref>}}

{{quote|"[U]nlike the mature Haydn, Mozart never came to write four movements without changing the keynote" ''[not actually true, but indeed it was much rarer for Mozart than Haydn once Mozart reached maturity]''<ref>Hans Keller, 'Wolfgang Amadeus Mozart (1756–91)', in ''The Symphony'' (Ed. Robert Simpson; London, 1966), p.75</ref>}}

{{quote|Just because Haydn is more adventurous in his excursions into [remote keys](/source/closely_related_key) than Mozart, he sometimes needs a rigid tonal framework in order to contain them; unlike Mozart and like Haydn, whose developmental modulatory creative character he produced twinlike, [Beethoven](/source/Beethoven) in his turn was to indulge in passionate tonal and harmonic contrast within homotonal frameworks.<ref>Hans Keller, ''The Great Haydn Quartets: Their Interpretation'' (London, 1986), p.39</ref>}}

Keller's coinage and concept have not become standard among musicologists.{{Citation needed|date=May 2018}} Musicologist William Drabkin, for example, asked the question "doesn't 'homotonality' sound a trifle queer?" <ref>William Drabkin, review of Hans Keller, ''The Great Haydn Quartets: Their Interpretation'', Musical Times, Vol. 127, No. 1726 (Nov., 1986), pp. 624–625</ref> 

The term 'homotonality' (referring to ''the manifest retention of a tonic'') should not be confused with '[monotonality](/source/monotonality)' (the theoretical position according to which a tonal structure has only one 'real' tonic, and all [modulation](/source/modulation_(music)) is superficial or illusory).
