Stride Piano is a style of jazz piano that emerged in the early 20th century, particularly in the 1920s. It is characterized by a strong, rhythmic left hand that plays a bass line and chords, while the right hand performs intricate melodies and improvisations. This technique allows for a lively and dynamic sound, making it popular in jazz clubs and dance halls. Notable Stride Piano musicians include James P. Johnson and Fats Waller, who helped define the genre. Their performances often featured syncopation and a playful, energetic feel, which contributed to the development of later jazz styles. Stride piano remains influential in jazz music today.
