Re: What can I practice while at work?
* Buy a Tuning fork and hit it and try to remember the note, do it every hour.
than sing the note and hear if you are close…after a couple months you are getting there.
Than hit it again and sing a different interval..continue with this with all intervals.
Try not to think in guitar diagrams/ grids, shapes or boxes you find on the net or in books its all finger memory..which is nice but limited on the long end.
Think in intervals , 1 to 12 with all the b (flats) and # in between on the guitar.
Now try to internal sing and visualize them on the guitar neck.
New ideas will come if you do it regularly , your ear will be better and it will give you a lot of musical freedom to play whatever you like.
When you come home after a day of hard work , put those exercises to work on your guitar.
