Swing

When "hot" big bands and "sweet" dance bands joined forces in the mid-1930s, the Swing era was born. Bandleaders like Benny Goodman became teen idols, while Nat "King" Cole led a much-copied piano trio and, along with vocalists such as Frank Sinatra, brought Swing ideals into extremely popular orchestral recordings during 1950s and '60s. Jump Blues lived up to its name by being a bluesier offshoot of Swing that featured a more pronounced rhythm. Mastered by Louis Jordan, this good time music led to the R&B and rock music.
