How long did it take you to memorize the fretboard?
What I mean is that each set of 2 strings repeat the same notes 2 frets up. So if you memorized the patterns for the E and A you pretty much got the whole neck if you extrapolate out diagonally. I learned the fretboard after thirty years, effectively, in about 2 hours with the super cluster method.
How much does fret trainer cost?
The design and function of the app are great. I had it installed and was playing my first notation game in about 15 seconds. There's a free version and a paid version. The paid version ($1.99) unlocks higher portions of the fretboard, and removes ads.
