CadenzaA suspended second
Asus2
Also written A2 (in some charts)
No 3rd: the 2nd takes its place, so Asus2 is neither major nor minor. Its three notes are also Esus4 — which one you hear depends on the bass.
How pianists voice Asus2
The same notes, laid out the way hands actually play them.
Open triad Spread
1 · 5 · 2 — root and 5th below, the 2nd an octave up. The same three notes spread over two octaves: the sound of strings rather than a keyboard.
Asus2 inversions
The same 3 notes with a different one in the bass. Each inversion is written as a slash chord.
Root position Asus2
Root at the bottom, stacked in 3rds: 1 · 2 · 5.
1st inversion Asus2/B
B (the 2) in the bass: 2 · 5 · 1.
2nd inversion Asus2/E
E (the 5) in the bass: 5 · 1 · 2.
