Bar - 

A vertical line through the stave, to mark the music into sections, each with a set amount of beats within.

Basso Continuo -

A choral work that uses solo voices with an instrumental (usually orchestral) accompaniment. A cantata is generally a choral work of some length that also uses solo voices, usually with instrumental accompaniment.

The practice has expanded to allow for any number of 'f's, depending on how loud a composer wants something to be played. Here are some examples of when 'fff' really doesn't describe it...

The piano evolved from the harpsichord, in that the piano creates sound by hammers hitting strings, rather than the strings being plucked.

A form with a recurring theme, usually used as the final movement of a sonata or concerto. Mozart's Rondo alla Turca is inspired by Turkish military marching bands from the 18th Century.

Rubato -

(Italian: 'stolen'). An instruction to play with freedom. Rubato allows performers to deviate from strict tempo regularity, and can enhance expressive playing. In essence, by 'stealing' time, or borrowing it, it should be contrasted with strict time, in a musically correct method of atonement.


Scale -

Scherzo -

(Italian: 'joke'). A movement from a work. Originating in the 17th Century, the form usually appears in a Symphony as a fast, light-hearted second or third movement. Beethoven used the form as an alternative to the minuet, and Chopin expanded the form as whole works in his four Scherzi .

Sonata -

(Italian: 'sonare', to sound). A composition for soloist, or soloist with piano accompaniment. The sonata usually consists of several movements with one or more in sonata form.
