I fall in love too easily is a famous song wrote by Jule Styne and Sammy Cahn.
A lots of musicians have played this tune but of course Frank Sinatra made it famous in the film Anchors Aweigh in 1945.
This is my interpretation played by guitar and voice, you can read the chords, the melody and lyrics under the video. The song is in key of C.
The theme begins where there is a sign with pencil.
