Question: Hello Albert, My inquiry today is:

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

– Achilles (Malta)

Albert’s reply: As described in Sonata kind Simplified, the an initial section the a movement in sonata type in the classic era (roughly 1750–1820) as exemplified by Haydn, Mozart and also Beethoven is dubbed the exposition. The exposition states both of the key themes or (more often) theme groups.

You are watching: In double-exposition form:

In a concerto featuring twin exposition (which eventually came to be the norm in the classical period), regularly only the initial orchestral exposition is a complete one, definition it introduce the key themes. The solo exposition that follows is no bound through the orchestra’s themes. (It can’t it is in overemphasized that great musical creates are first and foremost rigid – that is, they phone call a story – fairly than formulaic. Only mediocre or commercial music is written according to strict formulas, the last with advertisement emphasis, prefer one right now famous writer who wrote a bestseller by evaluating and copy the type of present ones.)

It is tempting to assume that twin expositions for instrument concertos occurred from timeless sonata form, however this turns out no to it is in the case. After all, the 2 were occurring concurrently, and twin expositions in concertos actually predates first-movement sonata form as it became known in the timeless era:

J.S. Bach’s child Johann Christian Bach’s very an initial published work, the Piano Concerto in B-flat major, Op. 1, No. 1 indigenous 1763, is (to my knowledge) the first known instance of twin exposition in a concerto. The very first examples the conventional classical sonata form occurred much later, in Haydn’s cable Quartets, Op. 33, i m sorry were composed in 1781. Haydn claimed of them the they were composed “in a completely new and special way,” introduce to his development of sonata form as a dramatic structure.

Rather, the dual exposition – in which very first the orchestra and then the critical soloist do two different expositions – come about much more as a advance of Baroque ritornello concerto form. The term ritornello (“little return”) refers to the return that the main theme by the orchestra. The soloist play in in between ritornelli, one of two people accompanied through the orchestra or not. This development from ritornello to classic concerto kind (featuring double exposition in the very first movement) is confirmed by the reality that in the latter, the soloist does no necessarily repeat the orchestra’s themes – sometimes not also the main theme.

Thus, as is usual in west music approximately the 20th century, developments in musical creates were evolutionary, not revolutionary, and the readjust from ritornello come sonata kind for the very first movements (and sometimes others) the multi-movement concertos is an instance of evolution change.

It’s essential not to confused two supplies of the hatchet “double exposition.” The hatchet is additionally used because that fugues that feature a full exposition (i.e., in all voices) with a brand-new subject. Remember the the exposition the a fugue is entirely different from that of a sonata!
