What has finally won me over is how beautiful - and useful - the score sheet is. Here's an example, the current piece I am arranging, click on it to show detail. How good is that!
- Clef notation is great because it gives you note duration. Tab does not normally give you note duration, but this "full tab" presentation does!
- Clef notation doesn't give you left hand fingering positions (unless specifically marked), Tab, by its very nature, does. Fingerstyle tends to wander all over the fretboard to get the fingerting resolves needed, so knowing that you need to play a C on the third string rather than the second string is important.
- Clef notation is hard to read when the notes go too far above and below the clef. Tab doesn't have that problem.
Let me know what you think!
