yes it does.
I find that the metronome has been particularly useful for me when I play the tenor banjo, because I use four fingers in single fret assignment getting my little finger to move at speed required work.
the electronic metronome was really useful, I was able to set it perhaps three notches lets say from 108 to 111, and gradually increase my little finger mobilty and speed, over about a month I was able to increase my competence so that I could increase the speed about ten notches.
I have also found it useful when teaching beginners guitar, suppose I wish to teach a complete beginner, to play in 4/4, using thumb index middle ring on 4321 strings, I can set the metronome very slowly, and get them to play each crotchet as a tick gradually increasing their speed as they become more competent, and somehow it works better than not using anything at all.
