I often choose to play fretted notes, when I have a choice between fretted and open notes. Even if the passage is more difficult, I typically use the fretted notes ... I like the tone and control of the note better. Typically, if the open note is a passing note, or "has" to be played to sound right, is the only time I use an open note. Anyone else prefer fretted notes to open notes ... ? Hmmm ... does it really matter?
