Like a lot of people here I am using my extra time to do a bit of woodshedding. I'm finding some great material, running arpeggios over the changes to Giant Steps, learning some Paul Chambers transcripts--just stretching myself musically. I came across an etude, and absent the written score, I do see the benefit of the ear training aspect of it. But musically I wonder if it's the best use of my practice time. It seems to me that I get the same benefit from looping the above mentioned actual tunes as both exercise and real harmonic content. At least when I'm done I can say I learned a real piece of music.
This is coming from a good ole boy that played music with his friends. I think we move to tunes when we start playing with others. Scales, arpeggios, etudes, etc. are done to learn something or some , i.e. how to play.
That said; I also think we find a time when sales and arpeggios are not part of our study time. Yes we may run a scale or two to warm up, but, we move to practicing the songs we will be using...
Played rhythm guitar in the same band for 15 years. Played the same 35 songs over and over. We gigged somewhere once a week, and because of that rust did not develop, so none of us practiced we just showed up and played. At Christmas we would get together and dust of our Christmas songs. If we wanted to add a new song, we would get the fake chord on that song and practice it as a warm up, at a gig for a couple of weeks.
My point, there is a time for study and there is a time to take what we know and just go play the music.
Playing music was a part of my life, along with several other things, like family, job, and things like that.
