I find it both useful and interesting but thatās just meš
Many famous musicians have no āformalā theory. They are naturally āgiftedā. Unfortunately, Iām not.
You can certainly get by without music theory knowledge, however for me even a little basic theory can be a great help.
For example:
Theory states; Chords consist of stacked āthirdsā.
But what is a third?
Itās just the third note in the sequence of notes making up a scale. CDEFGAB(C)
Big deal, why do I need to know that?
Well, a C chord consists of the notes C, E, G.
An E chord consists of the notes E, G, B.
a G chord would beā¦ā¦ G, B ,D and so on.
The 3 notes can be in any order and these different orders are referred to as āinversionsā.
See, not so difficult is it.
I use Every Good Band Deserves Fans And Cash as an easy way to remember the Circle of Thirds that make up major/minor chords.
EGB, GBD, BDF, DFA, FAC, ACE, EGBā¦ā¦
Take Standard tuning on a guitar, on any three strings, the top string will be a 5th, the middle a root and the bottom a 4th. (Check it out in Music Theory - Intervals).
So why should I know that ? Well, theory also tells us that next to any 4th, is a third. It sits one fret up towards the guitar head.
Theory told us that any Root, Third and Fifth, makes a major chord of the Root note. These notes can be in any order.
Knowing that, I can now make major chords and their āinversionsā anywhere on the guitar fretboard, not just at the guitar head.
Theory also tells us that minor chords have a āflattenedā third. Sounds complicated but simply means that if I fret the lower of those three strings that make up my chord, one fret closer to the guitar neck my major chord becomes minor chord.
Now I can play any minor chord or itās inversion anywhere on the fretboard.
Just a little theory and already I can play major, minor and chord inversions all over the guitar neck.
While not āessentialā , theory can certainly help you understand your musical journey and answer those questions that arise as your guitar knowledge grows.
Such as:
But, when I make a chord that has a third on the B string, the third (not the fourth) is directly below the root. Why?
The theory on Standard tuning intervals explains how the intervals between E-A, A-D, D-G and B-E are all 4ths but the interval between G-B is only a third.
Wait, what are Intervals?
The ādistanceā between notes. More music theoryā¦ā¦
See knowing and applying a little theory leads me to wanting/needing to know more.
