An educational game to learn the location of notes on the fretboard of the guitar and other stringed instruments. Eleven instruments are available, including bass (4/5/6 strings), mandolin, 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)

One Request!

Can you fix the game exiting arbitrarily? I’m using the 8 string guitar and very frequently, without any particular patter of usage, the game exits!

Other than that, I love this app! And you’ll love it too!

Okay application and too many adds

This app is okay. It would be nice to have it in landscape, but the notes do not rotate so it it too hard to use in that orientation.

This app is plagued with ads. Very so many interactions an ad will pop up. When you make a certain number of navigations an ad pops up. In a span of about 30 seconds I have 3 different ads pop up. It is annoying because you have to sit and watch them for a minimum period of time.

I do not believe I would recommend this app.

Way Too Many Adds

This app has potential, but once you get going, you are inundated with adds. If you play the game portion, you actually spend more time being forced to watch adds than playing. Of course, you can pay a fee to remove the adds. Why bother when there are other free apps that do the same thing. I finally deleted the app after getting tired of all the adds.
