Guitar
A guitar fretboard trainer that listens to you play
Learn every note on the neck by finding it with your hands.
Most players know the open strings and a few landmarks, then count from there. Counting works, but it is slow, and it falls apart when someone calls a chord you have to find right now. Fretrune trains the other way of knowing: you see the fret and the note is simply there.
How the drill works
Fretrune names a note, on screen or out loud. You play it on your guitar. It hears the note through your iPhone or Mac microphone and tells you straight away whether you found it. That is the whole drill, and it is built around three ideas:
- Playing is what counts. Finding a note on a picture is a different skill from finding it on your own neck, so only the notes you play move toward Solid.
- Speed counts. Fretrune keeps count of how quickly you find each note, and a note only reaches Solid once you find it quickly.
- Weak notes come back. The notes you are slow on or miss come up more often, and the ones you know come up less.

Where to start: the low E string
Practice begins on the thickest string, low frets first, and moves to the next string once you know it. The low E string is where most chord roots and bass notes live, so it pays off first.
When your guitar isn't with you
The No-Guitar Quiz keeps you going on the bus or in line. It asks about the notes you are working on in Practice and you answer on screen, from three choices: name the fret that lights up, or pick which fret on the string is the note it names. It doesn't change your levels. Those only move when you play.

Questions
- What is a fretboard trainer?
- An app or exercise that teaches you where each note is on the guitar neck, so you can find any note without counting up from an open string or a landmark.
- How is Fretrune different from a fretboard quiz?
- A quiz asks you to tap a note name on a screen. Fretrune asks you to play the note on your guitar and listens through the microphone, so what you practice is the thing you need: finding the note with your hands. It has a quiz too, for when your guitar is somewhere else, but only playing moves a note toward Solid.
- How long does it take to learn the fretboard?
- It depends on how often you practice. Short daily sessions work better than long occasional ones. Fretrune tracks each note separately, so you can see which ones you have and which still need work.
- Does it work with an electric guitar?
- Yes, through an amp or near the microphone. An unplugged electric is quiet, so play close to your iPhone or Mac, or in a quiet room.
