Thanks everyone. I've just got in from work and was very pleased to find all this advice which i shall be looking into. My instrument has four strings; the first a double course followed by two singles and I am experimenting with Ionian and Dorian modes although I realise that there are many others. As I said, I used to play it many years ago but only a simple strumming style. Sorcha,I now want to try a more adventurous finger picking style and yes, I do play the guitar although fairly basically as I am essentially a woodwind and bagpipe player.
Thanks especially for the history Sedayne and the playing description leeneia and katlaughing for the book tips. And thanks Les for...well just for being Les!
