Asus2 - La Suspended Second

In music theory, A suspended second chord is built on A-B-E formation: root-major second-perfect fourth. Suspended second chord has a formation A-E-A-B-E from basses to trebles in the guitar.

This suspended chord may be derived from a major triad or minor triad. In music theory, suspended second chords are built by three different notes and chords' suspend function is concluded by exchanging first third interval to a major second interval. These chords' main function is giving a suspend and resolution effect to its original(expected) triad form.
