The Gecko K17NOTE uses the Jazz A minor scale and has a tiered, lotus-style layout for its tines. The lower row of the tines (pictured in grey) has notes A3-G4#, while the upper row has A4-A5. (The Jazz A minor scale has the same notes as C Major, with the addition of F# and G#, which allows you to play some additional songs. It also has a more melancholy feel.)
