Dotted rhythms are a musical pattern where a note is followed by a dot, extending its duration by half of its original value. For example, a dotted quarter note lasts for one and a half beats, combining the length of a quarter note and an eighth note. This creates a distinctive, syncopated feel in music, often used to add interest and variety. In Western classical music, dotted rhythms can be found in various styles, from Baroque to Romantic compositions. They are also common in jazz and pop music, where they contribute to the groove and rhythmic complexity, making the music more engaging for listeners.
