Malachy, I'm a novice dulcimer player. I would suggest that you first read the threads above to refine your questions. (Maybe they are already answered or maybe the readings will make you think of more questions.)

What helped me most:

1) A good book (such as Jean's) that you can go back to periodically to refresh your memory and better understand the tunings.

2) a collection of tabs for songs I know and love. I read music so tabs are easy for me.

3) Concentrate on playing in one tuning (I like DAD) to get used to the basic chords in that tuning, then just fiddle around with making your own music, songs that pop into your head when you hear those chords.

4) The threads above will talk more about picks, tab sites, etc.

5) If you're lucky, find someone to jam with.

6) Buy tapes and CD's of dulcimer playing, (sold at festivals and music stores).

7) Search the Internet for dulcimer clubs and the things they are talking about. (players they recommend listening to)
