I’ve seen a few post on this site encouraging people who have expressed an interest in Mandolin/OM/Tenor guitar, to take up tenor banjo "to be heard in a session". This led me to think of a number of people I know who who rate the volume of their instrument over tone or other factors and proceed to play in every situation at full blast. I’m not having a go at banjos in particular, a session member here that I play with is a good example of varying his attack, palm muting the strings and playing up the neck to avoid destroying the mix. On the other hand, I’ve played with a guy whose concertina can make your ears bleed.
I play a quiet instrument (OM) because I enjoy it and so long as I can hear myself, I don’t worry if others can hear me.
A hammered dulcimer player turned up the other day and it was great to listen to a different voice in the mix, people actually backed off the volume to hear her play. It’s a pity this doesn’t happen more often.
