DS Music have put up a very useful free resource page for guitar and reading music.
There are well laid out sheets on reading standard notation and tab, as well as a host of useful guitar fretboard chords and scales (useful for both students and teachers of guitar).
For beginners, you can find, amongst other tools:
- Basic guitar chord diagrams
- Fretboard note layout
- Chord flash cards
For those going beyond basics:
- A sheet to explain the CAGED system
- A scale dictionary
- A useful explanation and diagram of the Circle of Fifths
Master Each Concept
It is worth taking your time with these resources, making sure you have mastered one scale or concept, and explored and integrated it into your playing, before moving onto the next. It is much better to have one scale that you can actually make music with, than to know loads that you can’t use! Working with a good teacher can help you manage this process. Finding ways to test yourself without looking at the sheets is also a good idea, as you don’t want to become reliant on them.
Uke & Other Instruments
If you play ukulele or another instrument, the standard notation and tab sheets still have a lot of useful info that can apply to any instrument. This is one of the advantages of standard notation over other methods of notation.
Keep Exploring
Also handy are the pages of blank chord, practise and notation sheets for you to fill in yourself. These are great for checking you have retained things, or for keeping a record of other chords and scales that you discover along your guitar journey.
