Question: Hello Albert, My question today is:

Where walk the idea of dual expositions in piano concertos come from and also how go it impact later compositions?

– Achilles (Malta)

Albert’s reply: As defined in Sonata type Simplified, the an initial section the a motion in sonata form in the timeless era (roughly 1750–1820) as exemplified by Haydn, Mozart and Beethoven is referred to as the exposition. The exposition says both that the key themes or (more often) theme groups.

You are watching: Which genre uses double exposition form?

In a concerto featuring dual exposition (which eventually ended up being the share in the timeless period), regularly only the initial orchestral exposition is a complete one, an interpretation it introduces the main themes. The solo exposition that follows is not bound through the orchestra’s themes. (It can’t be overemphasized that good musical creates are very first and foremost stare – that is, they tell a story – rather than formulaic. Just mediocre or advertising music is written according to strictly formulas, the last with commercial emphasis, prefer one currently famous writer who wrote a bestseller by evaluating and copying the kind of currently ones.)

It is tempting to assume that dual expositions for instrument concertos occurred from timeless sonata form, but this transforms out no to be the case. After all, the two were developing concurrently, and double expositions in concertos actually predates first-movement sonata type as it became known in the classical era:

J.S. Bach’s child Johann Christian Bach’s very very first published work, the Piano Concerto in B-flat major, Op. 1, No. 1 indigenous 1763, is (to mine knowledge) the an initial known instance of twin exposition in a concerto. The very first examples that conventional classical sonata type occurred much later, in Haydn’s string Quartets, Op. 33, which were composed in 1781. Haydn said of them that they were composed “in a fully new and special way,” referring to his breakthrough of sonata type as a dramatic structure.

Rather, the twin exposition – in which very first the orchestra and then the critical soloist perform two separate expositions – come about more as a development of Baroque ritornello concerto form. The ax ritornello (“little return”) refers to the return that the main theme through the orchestra. The soloist played in in between ritornelli, one of two people accompanied through the orchestra or not. This advance from ritornello to timeless concerto form (featuring twin exposition in the an initial movement) is confirmed by the fact that in the latter, the soloist does not necessarily repeat the orchestra’s themes – periodically not also the key theme.

Thus, as is usual in west music as much as the 20th century, advances in musical develops were evolutionary, no revolutionary, and also the change from ritornello come sonata type for the very first movements (and periodically others) of multi-movement concertos is an example of evolutionary change.

It’s important not to confuse two uses of the hatchet “double exposition.” The ax is additionally used because that fugues that attribute a full exposition (i.e., in all voices) v a new subject. Remember the the exposition the a fugue is entirely different from the of a sonata!
