Question:

"Tommeken says, "Hello there in the far west Playing for a few months all kinds of chords for now and i learned a few lessons from Jim and Steve about finger picking. Now i wanna learn some songs my daughter recognizes so she can sing along. Is there an easy way tot change those simple melody tabs from a songbook into a nice sounding finger picking tune with alternating bass. I mean songs like Alouette, country roads, and so on... Where to begin? what should i keep in mind ? scales? chords ? greetings and thanks for all those nice lessons... Tom""
