Pushing scale practice doesn't help improvising.

I used to have this problem in my first year playing guitar.  My first ultimate goal was "Far beyond the sun" by Yngwie Malmsteen.  Pretty ambitious for a beginner.  Accomplishing song by song, picking speed went up, left finger maneuver became fluent.  However, Yngwie Malmsteen style is pretty challenging.  If I remember that time, I practiced different scales in metronome.  One day, I could play "far beyond the sun."  However, the speed I play for Yngwie Malmsteen didn't help other songs.  I was puzzled.

Big Question. "I could cover fastest genre of the music, but other than his music, I am still struggling with other pieces.  Why? "

Having 10 years of gap without playing guitar, I can't play Yngwie Malmsteen as I did.  But, I can enjoy more music than back then I used to play.  Here is my answer about the question.

Improvising has two modes.  "Controlled progression" and "Shredding".  Controlled progression relies on current musical context.  What is the key signature/main scale?  What is the beat signature/and main rhythm? More importantly, controlled progression much relies on the brain, the most important tool for music.  Muscle movement works together with the brain.  Do you see that the limiter is "the brain"?
On the other hand, shredding depends less on the brain.  It heavily relies on muscle memory.  Brain just sets up basic information like "what code/what sclae" and "what major beat", then finger works all.  In here, detail is less important, such as order of notes  as long as notes are in scale, and diatonically working.

When playing in band, these come out somewhat mixed.  For example, Yngwie Malmsteen, many phrases are roughly 20% controlled, 80% shredded.  So, brain tells "From now, 4 measures will be diminished rooted 20th fret C down."  Then, during 4 measures fingers improvise without help of brain.  In the meanwhile, brain accepts the next phase, "stop at 8th C vibration, for the 4 beats, and then the last half beat will Bm harmonic minor in pulling manner."  After executing 4 measure, this should end at C, and pulling Bm harmonic scale comes up.  Sure while this finger is working, Brain just thinks the next, not the one fingers are playing.

When in shredding mode, accidentals are not common.  Because accidental is a big brain work.  "We make irregular note X, which is not in scale, but produces effects of A,B,C, and some alpha of tention.  It will be resolved by in scale tonic Y or 5th of Y, etc. "  These need lots of controlled work.  Fingers can't just dance on their own.  They will pay attention to the brain.

Now the key point here.  Increasing maneuverability in controlled work is the foundation to play variety of music.  At the same time, brain should have more tools to provide good signals to the fingers.  I will explain this further.
Here is a simple test how fast I can maneuver in controlled.
Simply pentatonic through 6 strings.(Low A(5th fret 6th string) to high C(8th fret 1st string).  Try beginning with down picking. Change the same play with beginning with up picking.  This is one example of controlled picking.
There are different patterns of controls like 3rd down (C-A, B-G, A-F, G-E, F-D, .... ), alternate/3 string sweep, etc.
If these maneuver is fluent, many things will be easier.  Plus, shredding speed will also increase.

At the same time, don't forget to listen to more good musics.  And catch ideas from the music.  Eventually, collection of these ideas will make brain lucrative to utilize, and improvising will be cool and sound.

Guitarists...

So, my favorite instrument is the guitar.  Practically, I only can play the guitar.  Many great musicians inspires me, but due to my limited time, when I get a chance to play it, I have to concentrate for just one thing.

Anyway, my favorite guitarist is "Jason Becker."  He is the god and the most fluent guitarist.  At the same time, he had many brilliant ideas.  Considering all of his work, which ended at his age of 29, he didn't have his best time, unfortunately.

Then, my favorite "active" guitarist is "Guthrie Govan".  He is very special, to tell the truth.  Most of guitarists have own color, specializing handful of genre, Guthrie doesn't have specialty.  He is really all-rounder.  Rock, Blues, Jazz (Classic, Beebop, fusion, plus some brilliant covers with different colors), and Country.  Picking, finger style, slap, tapping, arpegio, ...  He also plays very good acoustic.  His theory is very strong.

I recommend his videos in youtube.  None have disappointed me, so far.

Audacity slow-down calculator

*Note: this article is out-dated.  Or, no-worth.  I found that audacity fixed noise problem with tempo change.

If you play music, audacity is an essential tool for many useful things.  Copying music, Ear training, etc.  When slowing down original source using "change tempo", annoying noise mixes with proper output.   I walk two step to avoid noise.  "change speed" and "change pitch".

How much parameter to give to slowdown but no noise, no pitch change is calculated.

#!/usr/bin/env python

import os
import sys

a = raw_input("slow down percent (50% half speed): ")
target_speed = float(a)
target_pitch = ( 100.0 - target_speed ) / target_speed * 100

print "target pitch change: %2.2f" % target_pitch

About Enthusiasm

I read a Korean article (http://wangsy.com/blog/2012/10/passion/), and One made me think for a while is this:

요즘 드는 또 다른 생각이 열정이란 만들어 내는 것도, 지켜내는 것도 아닌 주어지는 것 같습니다. 마치 천부적 재능이, 말 그대로 주어진 것이듯 ,열정도 주어지는 것인 것 같습니다. 뭔가 매우 비관적이고 운명론적 사고관이지만, 요즘 드는 생각이 그렇습니다. 열정을 가져 보아라, 열정이 꺼지지 않도록 잘 지켜라는 조언은 천부적 재능을 받아 보아라, 왜 예쁘게 태어나지 않았니 라고 하는 것과 같은 부질없는 이야기 인 것 같습니다.

It's very difficult to argue or practically apply this sentence.  But, I want to say that the author is so brave to tell this, because this is hard to say or hard to find an answer in practical world.  After a while, I somewhat agreed.
