This tune (Birk's Works by Dizzy Gillespie) was posted on YouTube in June but originally video taped last year 2007.

I talk a little about bass lines and how to work on them.
So I was thinking of making some sort of chord etude and I thought, why don't I just comp through a tune. Then if you're working on comping you could learn this etude and analyze it.
So I took the changes to 'I Loves You Porgy' and comped simply through it. I played mostly quarter notes to keep things moving.
I'm curious is this is helpful to any of you.
Work hard on the modes. They are the foundation of the line!!
Locrian the crazy scale! The 7th scale degree of the major scale.
----------------------------------------------------------------------
Chinese translation for Chinese students
如果拿Locrian 音階和大調（major）音階來比較，Locrian音階多了降2降3降5降6降7音。
因為沒有完全五度（根音跟五音中間），所以聲響上沒有被解決的感覺。
單單只打這個音階覺得沒有被解決，所以通常用在minor7b5- dominant7b9,
例如Cminor7b5- Fdominant7b9 - Bbminor7
Locrian 是比較難的音階，可以練習在不同調式之間轉換，熟悉不同調式音階的聲音。
Lesson on Symmetrical Diminished Chord Scales
The mixolydian scale is the major scale with a flat 7. It's a very distinct sound, you've heard it all over the place.

Chinese Translation for Chinese students
All Blues 這首曲子都是用到Mixolydian 的聲音。
Latin music 中也很常用到Mixolydian 的聲音。
在爵士樂中，遇到屬和弦(Dominant)會演奏Diminished音階，或是Altered音階，或是不同的音階。
但是也有時候會用到Mixolydian音階。
如果和弦記號有降九音，也不能用到Mixolydian音階。要是九音（Natural 9th）才適用Mixolydian音階。
Sharp the 4!
Chinese Translation for Chinese students
如果拿Lydian 音階和大調（major）音階來比較，Lydian音階多了升4音。
西城故事最有名的片段，用到Lydian。在Disney音樂中也很常用到。
如果是四級大調和弦，通常會用到Lydian(因為Major #11)
例如Gmajor-Cmajor, C是G的四級，所以聲響上面還是都以G調為基礎，所以這邊的C就可以用到聲四音（#F）
