Music: Beat, meter, and counting subdivisions

You tap along to a chorus and sometimes land on strong beats, sometimes on offbeats—meter is the recurring grouping of pulses, while rhythm is how sounds actually sit inside that grid. Subdividing into eighths or sixteenths is not decoration; it is how you synchronise with other players and hear syncopation correctly.

Practical use: transcribing hooks, practising with a metronome, and reading lead sheets. Edge case: tempo changes and tuplets break naive counting; here assume steady BPM and simple note values. Interactive theory lessons clarify duration math [1]; Open Music Theory offers textbook-style explanations [2].
