Something I'm having fun / pain with now is arpeggios from Matt Raum's book Mandolin Technique Studies. They're kind of like scales only harder. It forces my left hand up and down into the 2nd, 3rd, 4th, etc. positions on the fretboard and my right hand across all of the strings for each arpeggio.
Initially, practice was very chaotic. It just did what I felt like doing, mostly practicing and learning new tunes. I used my home office as a practice place. I got myself a software metronome. Turn on metronome, layout music on desk, play.
After a while, I decided I wanted a space just for practice. Rearranged my living room. Got myself a music stand. Put up some shelves for music and books, and an old laptop with speakers. Now I have this space and it has a specific purpose. I try to set a specific time, doesn't always work but it's there. I don't schedule anything during that time and try not to allow anything to interfere.
I found a bunch of practice scales from Mickey Cochran at Folk of the Wood. Lots of different keys and left hand finger exercise. Those are always on the music stand. I warm up with Bb (b-flat) scales. Forces me to use all four fingers on the left hand and stretch.
I used to try to work on everything at each practice--tone, speed, tunes, chords, left-hand, right-hand, but I think spreading out my time like that was not so productive. Now, I'm trying to devote each practice to a particular thing.
Scales and arpeggios working on clear tone. Nice a slow.
Chords. Learning new ones. Developing finger strength and pain tolerance.
Tunes. Replaying the ones I've learned and learning new ones.
Speed. Playing tunes, scales, arpeggios, and cranking up the metronome with a focus on speed and clarity.
Right Hand. Working with right hand exercises--banjo rolls, cross-picking, tremolo.
It seems to me that focusing on a single goal over the hour or two that I devote to practice yields better results. There's always a point during a practice where I notice some small improvement, a sense of greater ease, a feeling that my brain is less involved and my hands know what they're doing.
Right-hand Exercise - I think I found this in the MandolinCafe somewhere, but I can't recall where. When I first looked at it, I thought it would be easy and not so useful. Was I ever wrong. I use this all the time.
Software Metronome (Free) - I love this thing. It's very versatile and light weight. If someone uses it, or is already using it, and hates the click sounds, I created new audio files using audio from an old style wooden metronome. They make the metronome during long practice sessions less annoying. Let me know and I'll post them. (Stay away from the Toolbox button. It generates a boat load of empty directories on your computer for other software packages that NCH offers for sale.)
I'm still looking for practice materials for chords and chord changes. If anyone's got some links or pointers, bring it.
