I recently got myself a fretless bass and so far I'm loving every minute of it, but I've run into a dilemma. I've been following Steve Baileys fretless lessons on proper intonation and doing the exercises found on Youtube. In the first part of the video he shows an octave exercise where you 'fret' a low F with the first finger followed by the octave with the third finger. This is to check your intonation and to build muscle memory. The problem is that I have servere problems fretting the octave with my third finger, that stretch is just too big below the fifth 'fret'. On my fretted basses I always use a 1-2-4 fingering pattern when playing below the fifth fret. So my question is; do I just suck it up and keep on practicing one finger per fret even though I can't actually do it and it hurts after a while? Or do I continue my fingering from fretted basses and go from there? Any inputs are greatly appreciated.
