"Sultans of Swing" is a song by British rock band Dire Straits from their eponymous debut album, which band frontman Mark Knopfler wrote and composed. Although it was first released in 1978, it was its 1979 re-release that caused it to become a hit in both the UK and U.S.
There is music in between the notes of Mark Knopfler's guitar playing.
On one level, music isn't defined as being non-stop sound played at the same tempo with the same notes and rhythm all the time. The spacing between the sounds is just as important, or else it would just be constant noise. But that is not how everyone will define music. It can be argued that the silence between the notes or sounds can't be part of the music itself because the silence exists no matter what, and it is music that gives us something to do with the silence. The definition depends on the individual.
