Leiva Strings Inc.
Leiva Strings Inc.

Leiva Learning Strings provides a method for teaching students how to correlate musical notes to the cumbersome fingering positions of any stringed musical instrument by color-coding each note. The seven different colors are set to match the seven natural notes (A,B,C,D,E,F,G,) in music theory. With our patented Learning Strings, individuals can learn to play and read sheet music by matching colors making stringed instruments as fun and easy to learn as they are in the video game Guitar Hero.
