An educational game to learn the location of notes on the fretboard of the guitar and other stringed instruments. Ten 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)

Absolutely the best guitar app for someone who uses musical notation, intervals, and a variety of alternative guitar tunings. It is intuitive and easy to adapt to your needs. This is a must for those experimenting with open tunings, while at the same time probably meets needs of someone who wants to learn the standard fretboard as well. Really a terrific app.

Yup, I was emailing that address.

I am glad you are still in business!

The app is a fantastic learning tool and I use it for the three instruments I play every day. I truly enjoy it.
