I've got this tapping thing that sounds good on fretted basses, but it sounds SOOO much more...expressive, on fretless. It also sounds soooo...out of tune. The RH tapping is all starting just above the octave, where intonation is a real bizzatch playing NORMALLY, but tapping is...dang. Just ridiculously difficult. Is there any advice? I hold my forearm about parallel for this method of tapping (it goes mostly up and down the strings, not crossing them where I would have my arm perpendicular) so is there any way I can adjust this position for fretless tapping? How do you maintain tapping intonation on an unlined fretless?
