I found that I sometimes lost my tempo though there was only one set of rhythms. The instructor said, at moments like this, just go for the bass beats. The low and heavy sounds did help to keep the rhythms steady.
There is the possibility of harmony when we play the djembe with strangers though everyone has their own rhythms. However, we might end up in cacophony when performing with people whom we think we know well. The instructor suggested that it's either because we don't know our tempos or because we do not listen to one another.
I want to be as firm as the bass beats. You can't lead me by the nose.
