Definitions and vocabulary

Concerto

A concerto is a composition for orchestra, usually in three movements, in which a featured soloist is accompanied by a full orchestra. 

Dynamics

Dynamics refer to how loudly or softly the music should be played.

Harmony

Underneath the melody are clusters of notes called chords, each of which sound different. These chords can stand alone, or they can support a melody.

Melody

This is the part of the music you can hum, whistle, or sing to yourself. You might call it a tune. 

Meter

This is the part of the music you can tap your foot to. You will usually find that the main pulses fit into groups of twos, threes, or fours. A march is “in two” (ONE-two ONE-two) while a waltz is “in three.”

Quintet

A quintet is a composition in several movements for five players. 

Symphony

A symphony is a composition for an orchestra, usually in four long, separate sections called “movements.” 

Tempo

This is the speed of the music. The speed may vary from very slow to very fast. Most composers use Italian words to describe the tempo: adagio, for example, means very slow; andante, moderate; allegro, lively; and presto, very fast.

Timbre

The specific kind of sound each instrument makes is its timbre. A flute sounds different from a violin, even if it’s playing exactly the same note.
