Chordex places a wealth of musical chord theory at your fingertips. It offers two modes of operation. In the first, you can select a chord and the app will list the notes in that chord, telling you both their names and their degree on the scale. You can also play the chord or individual notes on the built in tone generator. The second mode allows you to highlight notes on a virtual keyboard, while the app lists the chords that contain those notes in an order based on both how well they match and their obscurity. For example, if you select D and F, it is fair to say that D minor is a better fit than A flat diminished 7th, but both are options. Again, this mode lists the notes that make up each of the suggested chords and offers you the chance to listen to them all.

Stop counting up and down your fretboard, trying to learn the notes on your guitar. Stop using patterns and shapes to identify your notes. I did for years and went through app after app in the hope something would help me. I couldn't find one that me "learn the fretboard cold" - as Steve Vai advises! - so I built my own and used it. Now I finally know all my notes. Become a Fret Master and FINALLY learn the notes of your fretboard - you won't regret it! Get down the location of the note in your mind and then get it on your fretboard. Fret Master challenges you, with your guitar to memorise the notes and if you really can't find the note - the app offers a gentle reminder. You'll find as you use the app that your memory of the location of the notes will really improve and your knowledge of the fretboard. The app also tests your chord knowledge, knowledge of the Major and Minor Diatonic and Pentatonic scales, and Root notes for soloing - use the app however you wish to achieve your guitar journey goals! Each test offers handy visual reminders should your memory need a prompt. Make Fret Master part of your practice sessions! What you will revise and learn: - All the notes on the fretboard with your guitar in hand - Your memory of the notes - Major and Minor Diatonic (for the purpose of note learning) - Minor and Major Pentatonic (for the purpose of note learning) - Essential chords - Essential Seventh Chords - E Shape Barre Chords - A Shape Barre Chords. Features - Various timer settings, including a no timer option - Handy visual reminders of chords, note positions and scale patterns.
