British & American Musical Terms


Pete teaches primarily in British English — crotchets, quavers, minims. If you prefer American English — quarter notes, eighth notes, half notes — please just say. Either way, this page lines the two vocabularies up, one against the other.

Two names, one music. The American names are fractions of the whole note — halves, quarters, eighths — a system so logical you can hear the maths. The British names are older words that predate it: a little history in every bar. Musicians on either side of the Atlantic read exactly the same notation — only the words differ.

Note values

brevedouble whole note 8spans two full bars (rare today)
semibrevewhole note 4one fills the bar
minimhalf note 2two to the bar

Rests carry the same names on both sides: a crotchet rest is a quarter rest, a quaver rest an eighth rest, and so on. Dotted notes and triplets work identically in both systems.

Other terms that differ

stavestaff the five lines music is written on
semitonehalf step the smallest gap in Western music — one fret on the bass

leading noteleading tone the seventh degree of the scale, pulling home to the tonic
perfect cadenceauthentic cadence the V–I “full stop” at the end of a phrase
interrupted cadencedeceptive cadence V–vi — the ending that swerves somewhere unexpected
first-time barfirst ending the bracketed bars before a repeat, played first time through

Same word, different spelling

Metre / meter. The pattern of strong and weak beats — what a time signature describes — is metre in Britain and meter in America. The measuring device is a meter everywhere, which is why a metronome is never a “metrenome”.

Practise / practice. British English splits them: you practise (verb) your bass, and the thing you do is your practice (noun). American English uses practice for both. Either way, do it with and without a metronome.
