I'd thought I'd share a glossary of some of the terms used for those that may not be familiar:
TONIC: The main key of a piece
DOMINANT: The V chord. It's typically the chord right before the last one of a piece. So in "Happy Birthday" , it's the final "to" of " to you". In the "Star Spangled Banner" it would be "the" of " the brave"
Usually as you can tell, it's on a "T" letter.....
EXPOSITION: In what's called sonata form, which is essentially that of a concerto, the exposition is the opening set of materials/melodies/motives that make up the movement; often with the exception of the opening theme, in the DOMINANT. There follows the:
DEVELOPMENT: where said materials/melodies/motives, get treated in different keys, expanded, contracted, any number of devices applied to them, culminating in a usually triumphant return to the:
RECAPITULATION: The return of the original materials in their original form, and usually in the TONIC.
CADENZA: A section of the piece, usually after the conclusion of the RECAPITULATION where the soloist goes off on their own in a ( now a mostly) written exploration and further expansion of the materials. It has an improvisatory character, and generally quite virtuosic as well.
DOUBLE FORTE:( fortissimo) FF, very loud
PIANISSIMO: pp, very soft
I didn't mention the following perhaps in the talks but these terms come from forte and piano meaning loud and soft respectively.
