All chords are available as PDF files
I created a guitar string "bend map" for my Larrivee acoustic guitar to know how far I can bend each one of my guitar strings. The map shows where I can only bend a 1/4 step all the way up to 1-1/2 step bend. It takes some time, but you should build a bend map for your guitar(s).
If you want to know what a triad is in music then the answer is here. I give the definition of the four basic music triads: major, minor, augmented and diminished. Triads in music are the basis of all harmony and I have open and closed guitar chords for all the types of triads in music.
The diminished triad is one of the four triad types in music. It is a chord that is unstable and has an extremely strong tendency to resolve to the tonic of the scale. From the diminished triad, you can build the fully diminished seventh chord, half-diminished seventh chord, as well as other diminished chords.
Music intervals and the chromatic scale are the results of dividing an octave into 12 equal parts known as semitones. Once you know all of the music intervals, then you can build any scale or chord based on the intervals that comprise them. Intervals and the octave are fundamental aspects of music theory and are easy to understand.
Learning and practicing the notes of the chromatic scale on guitar is crucial for speed, dexterity, fretting & picking hand coordination. It also helps you learn the notes at every fret on every string. I define the chromatic scale and its notes in a few different ways. I also have some practice exercises and graphics to help you learn this scale.
