downbeat

The first beat of a bar — the strongest, most emphasised beat.
The downbeat is beat one of any measure — the moment of greatest rhythmic weight in any time signature. The term comes from conducting, where the conductor brings the baton downward on beat one. In common time (4/4), the downbeat carries the strongest accent, with beat three as a secondary stress. The upbeat (or anacrusis) leads into the downbeat, creating the fundamental strong-weak pattern that drives all metered music.
The downbeat provides the listener's primary rhythmic anchor. In orchestral music, the timpani and double bass often reinforce the downbeat. In rock and pop, the bass drum and bass guitar typically land on beats one and three. Jazz swing places the emphasis differently — the rhythm section accents beats two and four (the backbeat), giving swing its characteristic lift. Reggae goes further, deliberately weakening beat one entirely. Syncopation works by placing accents where the downbeat isn't, creating rhythmic tension against the expected pulse. Understanding the downbeat is fundamental to understanding rhythm, meter, and groove.
