noteverdier

Noteverdier are the values assigned to musical notes that determine their duration within a piece of music. In Western music notation, each note symbol corresponds to a specific length of time, measured in relation to the beat defined by tempo and time signature.

Common noteverdier include whole notes, half notes, quarter notes, eighth notes, and sixteenth notes. In standard time, a whole note lasts four beats, a half note two, a quarter note one, an eighth note a half beat, and a sixteenth note a quarter beat. Dotted notes extend the duration by half of the original value. Triplets subdivide a beat into three equal parts, producing notes that fit within the same beat or pulse.

Notes are drawn with different shapes, stems, and flags to indicate these values. A note can be connected by ties to sustain across bar lines, and rests provide equivalent durations for silences. The tempo marks (for example, a beat per minute) tell how fast the beat moves, while time signatures (such as 4/4 or 3/4) define how many beats are in a measure.

Noteverdier form the basis of rhythm and meter in composition and performance. They are taught in early music education, used in notation software, and serve as a common language across styles. See also rhythm, meter, tempo, and notation.
