Guitar Arpeggios is app to learn arpeggios on guitar neck. It has arpeggios for standard and some drop tunings.
An arpeggio is a type of "broken chord" where the notes that compose a chord are played or sung in a rising or descending order. Arpeggios create a fast, flowing sound. Arpeggios always sound good over their matching chord in a progression, therefore, they generally form the melodic home bases and safe notes for improvising guitarists.

Guitar Intervals is an app to learn intervals on guitar neck. Click on the note to play it. It has intervals for standard and some drop tunings.

Intervals are the distances between any two notes. All harmonies or melodies can be considered as a sequence or layering of intervals. The quality of an interval can be Perfect, Diminished, Augmented, Major, or Minor.

All apps have right-handed and left-handed modes and can be useful for both novice guitar players and advanced players.
