Leading a Jam
General mountain dulcimer or music discussions
First of all....Kimberly i'm so pleased to see you posting!- I'm a big fan of yours.
Rob has given some great tips already.
My 2 cents- If you are 'leading' the jam you may have a certain short set list in mind that perhaps you have let the group members know about in advance. Still, it's good to also allow folks to go around the circle at least once and be able to choose a favorite tune for everyone to play. Two hours should certainly allow for all this.
The important thing about that is that it can allow a relative beginner to start a tune they know, at a tempo that is do-able for them. I feel that when someone at a beginner level chooses a tune, they should be allowed to have it NOT speed up. I remember how bad i felt long ago at my very first club setting when I was a beginner player -- every single tune would eventually speed up so that I had to drop out. I certainly understood this and everyone knew I was a rank beginner, but I looked forward to being able to start my one tune at my pace when it was my turn. It was finally my turn to pick a tune. I began the tune very slowly, as that was the best I could do. Several more advanced players very quickly sped it up and half way through the first time through it, I couldn't keep up with my own beginner tune, and had to drop out. That felt really bad.
As the group leader, you can prevent this from happening. You could handle it by starting the jam with a welcome to the new beginners, and by assuring them that if they start their own tune slowly, everyone will follow and respect THEIR tempo and not speed it up. Indeed, if others speed it up anyway, you can after the tune ends then say "OK let's play that tune one more time through but SLOWLY this time so we can all play together".
This is also the reasoning behind having some time set aside for a slooow beginner session or a beginner teaching help session. No one should go home from a jam without being able to play through even one tune to the end. A separate beginner help time would accomplish much the same goal, HOWEVER I still think it's important for seasoned members to be able to adapt to different tempos set by whoever starts a tune, and learn to not run roughshod over others simply because they themselves 'can' play everything fast. Playing well in a group is a SKILL that requires the ability to adapt to others in order for the group as a whole to succeed and sound good, after all.
Tunes can be at varied tempos...some can be expressive and slow while others can be fast and lively. Then everyone can have a good time!
Two hours can get eaten up pretty quickly by pre-socializing, late arrivals, announcements, tuning issues and broken strings, book/stand/chair shuffling, and misc talk. If you add a half hour of slow/beginner help, I think it should not be a part of that 2 hours, but rather come first and be in a different spot to the side if possible, to discourage seasoned players from joining in or disrupting it.
