G                                           Am
   Swimming, Swimming, Swimming, Swimming, Swimming, Stay in your lanes

Etc Etc....From what I can hear its G to Am for the entire verse and Bridge but the 
has slower strumming...Listen to the song to get a better idea!

Chorus:

*one strum


D*          Am*       C*       G                     
  Am
  Latchmere's got a wave machine Ooh ooh ooh oohooh ooh ooh ooh ooh oohooh

G                     Am
  Ooh ooh ooh oohooh ooh ooh ooh ooh oohooh


The change at the end:

D         Am       C    G      Am   C
Stay, Just stay in your lanes
