In previous lessons we’ve explored both major triads and minor triads, which are two of the most commonly used triads. In this lesson we round out the triads of the major scale with a look at diminished triads.

Seventh chords are chords that include the root plus the 3rd, 5th, and 7th intervals above the root. Another way to think about it is a seventh chord is a triad plus a 7th interval.

Slash chords are chords in which a note other than the root note is in the bass position. You might think this sounds very similar to chord inversions and you’d be right.

The circle of fifths is an invaluable tool that reveals important relationships between pitches and organizes them in a way that’s very useful to understanding diatonic harmony.

If you’ve been exposed to at least a bit of guitar theory, you’ve most likely heard of the CAGED system. It’s a system that allows you to visualize the guitar fretboard by using common major chord shapes.

In this lesson we’re going to take a look at how to read scale diagrams. Scale diagrams are used all throughout this site to visually represent scale shapes and patterns on the guitar.

In this lesson we’re going to dive into the ever popular C major scale. This scale is very common and is used as the key center of countless songs. It’s happy sounding scale and typically one of the first scales guitar players learn.

In this lesson we’re going to take a look at the major 7th, minor 7th, and dominant 7th arpeggios. These arpeggios are very similar to the major and minor arpeggios, but with an added 7th interval.

The A minor pentatonic scale is one of the most widely used guitar scales of all, particularly in the blues genre. In this lesson we’ll take a deep dive into the scale and explore some examples of its many uses.
