Hi Bob,

I neglected to answer one other question you posed. You asked what the difference was between Asus and Asus4 and does the designation "Asus" imply Asus4. Asus does indeed imply Asus4. May I suggest you sit at your keyboard and play the notes G, B, and D (G major), then play G, C, and D (Gsus4), then play G major again and you will hear the difference clearly, will feel the tension when you play the suspended chord, and the sense of relief or rest when you play the G major chord again.
