Q: you've said you notate a sus2 chord as a C2, for example, instead of Csus2. i was watching a video of a transcription on youtube and they had a Bb2 (and it was a sus2 chord indeed). would you say people are generally familiar with that chord symbol or could it be confusing to some?
A: i used to assume that other people don't do it this way, because i just made it up for my own convenience. but as i look around i see that indeed other people do use it this way. still just to be on the safe side, if i were making a chart for a stranger i might say sus2 just in case
