An educational game to learn the location of notes on the fretboard of the mandolin. Eleven instruments are available, including guitars (acoustic and electric), bass guitar, ukulele and banjo.

You are presented with a random note on the fretboard, and are offered a variety of choices for the correct answer. Just pick the button corresponding to the correct choice to score a hit!

The new staff training mode also helps you learn the position of notes on the musical staff on the fretboard of your instrument.

As your score gets better and you manage to identify notes faster across the entire fretboard, your working knowledge of the instrument increases!

Game mode provides a fun way to make progress. Work your way through levels of increasing difficulty and compete with your friends!


“ Learning the notes on the fretboard is key to any guitarist's development on the instrument, and [Fretuoso] is a neat way to get that info burned into your brain without having to carry a guitar with you everywhere you go. Pretty cool! ”
-- Bryan Beller (Dethklok, Steve Vai, Mike Keneally)

“ This is one of the best apps I've seen in a while. It's simple, fun and educational. Very useful for guitar players as a lot of [them] tend to play by ear and not care much about knowing the fretboard. ”
-- Rick Musallam (Mike Keneally, Gryphon Labs)

Great help

I purchased an Eastman mandolin but have no music background at all. This along with other tools has helped me get a start

Ok but sound does not work and developer will not fix

This is useful but one of the main reasons I paid was for ear training with notes sounding. The sounds do not work and the developer would not help beyond saying my phone was muted. It is NOT muted and the developer would not help. If you want hearing notes do NOT buy this app!

This app definitely helped me to learn the notes on the fretboard. It has made playing the mandolin more enjoyable and given me more confidence.
