coda

(Italian for "tail") a final and concluding section of a musical composition

sonata-allegro form

a dramatic musical form that originated in the Classical period involving an exposition, development, and recapitulation, with optional introduction and coda

minuet

a moderate dance in 3/4 though actually danced in patterns of six steps, with no upbeat but with highly symmetrical phrasing

fugato

a short fugue set in some other musical form, such as sonata-allegro or theme and variations

ternary form

a three-part musical form in which the third section is a repeat of the first; hence ABA

trio

an ensemble, vocal or instrumental, with three performers; also, a brief, self-contained composition contrasting with a previous piece, such as a minuet or a mazurka; originally, the trio was performed by only three instruments

serenade

an instrumental work for a small ensemble originally intended as a light entertainment in the evening

exposition

in a fugue, the opening section, in which each voice in turn has the opportunity to present the subject; in sonata-allegro form, the principal section, in which all thematic material is presented

recapitulation

in sonata-allegro form, the return to the first theme and the tonic key following the development

transition

in sonata-allegro form, the unstable section in which the tonality changes from tonic to dominant (or relative major) in preparation for the appearance of the second theme

development

the center-most portion of sonata-allegro form, in which the thematic material of the exposition is developed and extended, transformed, or reduced to its essence; often the most confrontational and unstable section of the movement

retransition

the end of the development section, where the tonality often becomes stabilized on the dominant in preparation for the return of the tonic (and first theme) at the beginning of the recapitulation

relative major

the major key in a pair of major and minor keys; relative keys have the same key signature, for example, E♭ major and C minor (both with three flats)
