"What a Wonderful World" is a song written by Bob Thiele (as "George Douglas") and George David Weiss. It was first recorded by Louis Armstrong and released in 1967 as a single, which topped the pop charts in the United Kingdom. Thiele and Weiss were both prominent in the music world (Thiele as a producer and Weiss as a composer/performer). Armstrong's recording was inducted in the Grammy Hall of Fame in 1999. The song gradually became something of a standard and reached a new level of popularity and it has been used in many movies. This arrangement for clarinet quartet (Bb Clarinet 1 or Eb Clarinet, Bb Clarinet 2, Bb Clarinet 3 or Eb Alto Clarinet, Bb Bass Clarinet) is suitable for repertoire, classroom and recital.
