I still learn the music theory – it helps to expand my horizons on guitar. See below my Top 5 resources for learning guitar fretboard, ear training and studying theory of music in the part that has the most practical impact of my playing: harmony and chords theory.
- A good book about guitar fretboard.
I have read a bunch of book reviews on acoustic guitar forum and on Amazon, and picked one that fits my level of playing and my style the best. It’s Guitar Fretboard Workbook by Barrett Tagliarino (affiliate link to Amazon.com). It is concise (80 pages), very well written and easy to read, has variety of exercises and is very practical. I highly recommend it.
- Fretboard Grids.
The book has fretboard grids for exercises, but I wanted extra sheets to practice more. I drew my grid version in Microsoft Excel and printed out a bunch of them. Then I converted Excel file to Adobe pdf format and attached to this post. Enjoy! Fretboard Grid (pdf) (1840)
- Software for Ear training
I use EarMaster 6 software (Amazon affiliate link) for ear training. It was very useful for improving my recognition of intervals and chords. This software has a ton of exercises for guitarists (and not only for guitarists), is very well organized, highly configurable and intuitive.
- Audio/MP3 Files for ear traning.
I found an excellent product for in-car or on-the-walk ear training: Jamey Aebersold’s Jazz Ear Training (Book & 2-CD Set) (affiliate link to Amazon.com). It’s a small book with two CDs. There are plenty ear training exercises on those CDs teaching you how to recognize intervals, triads, full chords with all possible alterations, and up to the harmony-rich musical fragments. I listen to them all the time and enjoy it very much.
- Music Theory Bible.
During my childhood, I tool piano lessons for almost 3 years. Then I played piano from time to time just for fun. I know the basics of music theory, but I wanted to have a reference book that I can use as a basis for building up my knowledge of harmony. Again, based on recommendations from the members of the Acoustic Guitar Forum, I picked up The Jazz Theory Book by Mark Levine (Amazon affiliate link again). It is not so easy to read, but this book provides exactly what I wanted – a full-scale course about Jazz Harmony and Chords Theory.
That is it. In my past 10+ years of the most conscious playing, I have used many books, software and approaches, but those five are my current favorites. You can find more resources on my Resources page.
