The 3/4 time signature is a musical meter that consists of three beats per measure, with each beat represented by a quarter note. This means that in every measure, you can count "1, 2, 3," and each count corresponds to a quarter note. The 3/4 time signature is often associated with waltzes and other dance forms, giving music a flowing, graceful feel.
In sheet music, the 3/4 time signature is indicated at the beginning of a piece, typically following the clef and key signature. Musicians playing in this meter will emphasize the first beat of each measure, creating a strong downbeat followed by two lighter beats. This pattern helps establish the characteristic rhythm of waltz music.
