Diatonic Arpeggios in G Major
An arpeggio as it relates to music is similar to a broken chord. The only difference when playing a broken chord is that you are more than likely playing the notes of the chord out of sequence of how the chord is spelled, when playing an arpeggio the notes are in sequence of how the chord is spelled. For example the notes of an A dominant seventh or more commonly known as an A7th chord are A, C#, E and G. When the notes are played in that order it would constitute an arpeggio. The same would apply going backwards as well. Example A dominant seventh chord going backwards would be A, G, E and C#. The notes that are adjacent to one another are not skipped or missed.
In the Major key of music theory the dominant seventh arpeggio scale and chord structure is derived from the Mixolydian mode. The dominant seventh arpeggio can also be found in the Harmonic Minor key and the Melodic Minor key. Although the Arpeggio and chord structure always remain the same, the scale derived from these modes will be altered, giving the Arpeggio and chord structure different tension notes when the chord or arpeggio is extended. For example a C dominant seventh chord derived from the Mixolydian mode would have the extension notes D, F and Bb added to the C7th. Whereas the C7th chord derived from the 5th tone of the Harmonic Minor scale would have the notes Db, F and Ab added to the arpeggio or chord extension, This mode is referred to as the Phrygian Dominant Mode. Lastly the C7th derived from the Melodic Minor scale would have two dominant seventh chords present. One would be derived from the fourth degree and one derived from the fifth degree extensions from the fourth degree would be D, F# and A added to the arpeggio or chord structure. This mode is referred to as the Lydian Dominant mode. The extensions from the fifth degree would be D, F and Ab added to the arpeggio or chord structure.
Diatonic arpeggios simply means the arpeggios are built from the notes of a certain key or tonal center. For example the arpeggios G major 7th and the arpeggio D7th are derived from the key of G major. G major 7th Being the 1 chord and D7th being the 5 chord of that key.
In the video below I will demonstrate all the arpeggios derived from the G major scale. I will demonstrate across the fretboard and also up and down the fretboard of the guitar. There will also be grids for you to follow while the video is presented.
