Dear Roman and all, is there really any experienced lute player, who does not correct his/her intonation towards pure while playing? It is easier to the viola da gamba players, of course, but very possible to us lutenists, too! Even if you do not want to set your frets to non ET, you can easily sharpen or flatten your notes - especially in higher positions. Roman, do you really just "push the buttons", or have you already found the enjoyment of coloring the pitches?
If not, try it. And then welcome to the gang! ;) Arto To get on or off this list see list information at http://www.cs.dartmouth.edu/~wbc/lute-admin/index.html
