What I love about Ariana Grande's sound is that she keeps jazz and R&B relevant. In this song "Only 1", you'll find a staple jazz chord progression called the 2 - 5 - 1. If you spent any time playing jazz standards, then you'll have come across this chord progression. Even though the song is one loop long, we have three instances of 2 - 5 - 1. Its awesome as a music teacher and guitar player! Learn what I'm talking about in the above video. I'll show you how to play some jazz chords - watch out, they go by quick! Use the chord chart below to fit the chords to the words. Enjoy!
