Glossary of Musical Terms

Badinerie (French: teasing), indicates a piece of music of light-hearted character. The best known badinerie is the lively last movement of Bach's Suite in B minor for flute, strings and continuo.

The bagpipe is an ancient instrument, at least in its most primitive form, and is still found in a number of countries. It is a reed instrument, with the reed sounded by air expressed from a leather bag. It generally makes use of a single pipe that can be fingered to produce different notes, with additional drones, pipes that produce single notes, a marked feature of bagpipe music and of its imitations for other instruments.

In written Western music the bar-line came to be used, a vertical line through the stave, to mark metrical units or bars (= measures). By the later 17th century the bar-line had come to be used immediately preceding a strong beat, so that a bar came to begin normally with an accented note. The double bar or double bar-line marks the end of a section or piece.

The word 'baritone' describes a type of male voice of middle range. The word is also used to specify pitched and valved brass instruments of lowish register and as an adjective to distinguish the rare lowest member of the oboe family, also known as a bass oboe, sounding an octave (eight notes) lower than the normal oboe.

The word 'bass' describes the lower register and lower sonorities in music. In vocal music it indicates the lowest type of male voice, and in instrumental music is generally used to indicate the bottom part. As an adjective it is used to describe instruments of lower register, such as the bass clarinet. In common speech the word bass may indicate the double bass, the largest and lowest instrument of the string family, or, in brass bands, an instrument corresponding to the orchestral tuba, the bass of the brass family.

The basso continuo or continuo is the figured bass commonly used in music of the baroque period. It was the normal practice to make use of a bass instrument of some kind, for example a cello or bass viola da gamba and a chordal instrument, a keyboard instrument or plucked string instrument, the part of the latter indicated by numbers added to the music for the bass instrument, showing the chords as a basis for improvised accompaniment or 'filling in' and embellishing of harmonies.

The beat or pulse in a piece of music is the regular rhythmic pattern of the music. Each bar should start with a strong beat and each bar should end with a weak beat. These may be known as the down-beat (strong, at the beginning of a bar) and the up-beat (weak, at the end of a bar). Up and down describe the gestures of a conductor, whose preparatory up-beat is of even greater importance to players than his down-beat.

Bewegt (German: agitated) is used as a tempo indication meaning something the same as the Italian 'agitato', although mässig bewegt is used as the equivalent of allegro moderato.

A bourrée is a duple-rhythm French dance sometimes found in the baroque dance suite, where it was later placed after the sarabande, with other lighter additional dances.
