Okay, Csus = added 4 from the scale. So F C2= added 2 from scale. So D Csus2= ???? Is it both the 4 and 2 added, or something totally different? This is mainly for my guitar playing, but it would be helpful for bass as well.... Thanks ahead of time I can't help but feel like this is a dumb question, but it's been bugging me for a long time haha.
