This is a test. I repeat, this is only a test. OOPS I almost said a political sentence. Instead I will tell you I'm old enough to remember duck & cover under my desk at school. Shoot, it's the same now. Glad I'm not in school.
For some reason, I see you and I think VICTIM. Maybe it's the warm and fuzzy avatar. Victim = stupid question from moi
How do I customize this T ? I guess you can see in my profile, right ? I managed to get my bird dog there, I THINK, but I want to add text. Got a minute?
"On a scale of 1 - 10 how important is it to you personally to learn/master the minor pentatonic scale? Seems as though whenever I run into the subject online emphasis enough cannot be placed on learning this "alphabet." So the real question is: Am I just spinning my wheels, wasting precious time, memorizing the five patterns and practicing speed build-up? Should I move on, or continue to pluck away at this boring stuff?"
I don't know, what other boring stuff would you be learning? Learning how a scale - or specifically the Major scale - has been constructed and how the scale should sound are the backbone of practical music theory. I really can't think of a reason why you shouldn't have at least the basics of music theory in your head if you want to play music. You can play well without knowing a lot of theory, but if you try to create music, it just comes easier when you have at least the basics of how everyone else has done it in your head.
If you are only learning the pentatonic patterns and ignoring all other scales - particularly the Major scale, yeah, you're wasting your time. If you are only learning patterns and not learning the sound of the scale - the sound of landing on the root and the distance between the root and, say, the third and why hearing that in your head is important - and experimenting with turning scales into music, yeah, you're wasting your time.
How many patterns should you know? How many do you think you might use? Depending on the genre of music you choose to play, you may not use any. That doesn't mean you shouldn't know the sound of the scale and how to apply it to music. Because the pentatonic is heavily used in many genres, there are more ways of teaching and learning the pentatonic than any other issue of practical guitar theory. You may be wasting your time just learning boxes if you can get away with using just the "frying pan" pattern or the "toothbrush" pattern.
It sounds as though you are self teaching yourself the pentatonics. One of the most common problems of self teaching is the teacher doesn't know what the student needs to learn next. So both the teacher and the student waste a lot of time.
Speed build up? Again, how fast do you need to play?
Basically, if you can't take theory and skills and turn them into some form of music, yeah, you're wasting your time.
Sure you can do it. There are many metal/rock songs which have acoustic part. You still can do the rhythm parts which have distortion. The sound is not exactly but it's not the problems. You can try some Metallica's songs: Nothing else matters, Fade to black, One, etc.
However, the solo part is hard when playing by acoustic. You still do it but it will be harder and the sound is not right enough.
It's better if you have an electric guitar and a guitar amp with headphone but if you can't have an electric guitar right now pick up your acoustic guitar and play. Don't worry
Try to play scales with some backing tracks. It will help you more exciting on practice and play music.
When you play with a backing track you will notice how the scales react with chords.
And practice everyday with scales, be patience and your hand will move on scales naturally one day
