As my peers state, going into guitar with the desire to learn basic chords, as well as building on a foundation of music theory can be very overwhelming, although the way you dive into this discipline can change your entire experience.
Beginners should dive into learning basic chords and notes on the fretboard. Learning the basic chords and the notes within the first few frets of the guitar will form a great foundation that you can apply throughout the entire guitar.
- this will provide familiarity and as a guitarist you will observe the same notes anchoring their respective chords
As you continue your practice and develop your techniques more, understanding theory will give you a universal understanding of the music you are playing. Continuously being conscious of the chords and notes you are playing and their relation respective to theory("What scale is this in?") will emphasize your capabilities as a musician.
- You will understand the scales your favorite songs are located in. For further pursuits, you may grow the skills to add or expand the riffs of songs you already love.
- You can grow to learn by listening - observing the pitch of notes and their orders, after experience and understanding, finding those scales and those exact notes will come naturally.
I like to expand my theory knowledge along side my technical skills by playing scales and listing each note in my head - this has increased my understanding and familiarity with the guitar and has made this practice transferable to instruments like the piano - though, respectively, an entirely different instrument requiring it's own philosophies.
