'Waltz', or valse from the German term, is a piece of music in triple meter, most often 3/4 but sometimes 3/8 or 6/4. A waltz has a 1.2.3. - 1.2.3. count and (generally) a slow tempo. Waltzes typically have one chord per measure, with the root of the chord as the first note.
Classical composers traditionally supplied music for dancing when required, and Schubert's waltzes were written for household dancing, without any pretense at being art music. However, Chopin's 19 waltzes (five he wrote as a child), along with his mazurkas and polonaises, were clearly not intended to be danced to. They marked the adoption of the waltz and other dance forms as serious composition genres.
Other notable contributions to the waltz genre in classical music include 16 by Brahms (originally for piano duet), and Ravel's Valses nobles et sentimentales for piano and La Valse for orchestra.
The waltz style is found in nearly every kind of European and Euro-American folk music and also in classical music. Although waltzes are often associated with the dance of the same name, not all waltzes were composed as dances: some were written for concert performance.
The waltz had once held so much importance in European music circles that great waltz composers received the honorary title of “Waltz King”. The title came with an accompanying “royal staff”, a decorated silver baton which was passed from musician to musician. Johann Strauss Junior, the most famous “Waltz King”, received the title frequently.
