Explanation

Improvisation is making it up as you go along, like taking a long stroll with no destination in mind and walking down random streets for the fun of it. Making choices that aren’t planned ahead of time, that’s improvisation. Jazz musicians are masters of improvisation, creating saxophone solos off the top of their heads based on what they feel in the moment. The Latin word improvisus means “unforeseen,” and improvisation happens when you can’t see the end goal but you keep moving ahead, dealing with obstacles in a creative way.
