Unfortunately, I don't have even 2 hours per day for practice. I just started a new job and am working 13 hour shifts. That has thrown a monkey wrench into all my plans. Also, I'm working out of town half the week and am only home the other half. I'm not complaining, I'm glad to have the job, but a lot of my personal plans and goals are being reexamined.
I'm not a full time musician like some guys here on the forum, but my work in a Rock 'n Roll cover band has kept me gigging almost every weekend for over 3 years now. The sight reading exercise is for my personal satisfaction more than anything else. I've never had any need to sight read for what we currently play.
I picked up a software program to drill on the bass clef and mastered that program in less than half an hour. So I don't have any problem recognizing the notes on the staff. Now I'm trying to associate those notes on the staff to the fretboard so I can play bass sheet music without thinking (like when I played sax back in band).
I picked up a Bass and Drum Styles instruction book that has bass sheet music in standard notation. I hope to play along with the backing tracks as I read the music. Each style has about a 6 minute backing track that goes with the exercise. Also, I recently signed on to a bass guitar instruction program on the internet where you learn songs. The instructor sends out .pdf files of the bass music in SN, and in SN+tab. So if I'm learning a new song, I'll be working on the SN alone first.
Because of my new job, and limited free time, I have to prioritize my practice time and prepare for our weekend gigs. At least the Styles instruction book and the program I signed up for on the internet both provide me with some sight reading exercises that I can apply directly to my bass playing in the cover band.
Honestly, before I got this job, I would practice 2 hours per day. Now, however, my goal is try to get in 30 minutes per day. So far, that has been too much of a challenge, especially when I'm out of town working the 13 hour shifts.
Anyway, thanks for the suggestion. I'll keep it in mind for the future.
