Tutorial - How to create "Okinawan Strings Quartet" by changing musical scale
This page is a tutorial of specific usage of ACS.
You will learn music through ACS by operating parameters such as "Scale", "Time Sign", and "Basic Beat" and by seeing how they influence music.
What is Musical Scale?
To put it simply, what musical scale means is how to make music by using "Do Re Mi Fa So La Ti". For instance, if you use only "Do Mi Fa So Ti" in your music, it will sound like Okinawa music no matter how you make it. This musical scale of  "Do Mi Fa So Ti" is what we call "Okinawa Scale".  (There are various other ways to call "Do Mi Fa So Ti".)
Musical scale that uses all of "Do Re Mi Fa So La Ti" sounds is called "Diatonic Scale". For instance, major music in Europe and USA such as Pops and Classical music are in diatonic scale.
Does Musical Scale Have a Strong Impact on Music?
Musical instruments, rhythm, and accompaniment are some of the factors that decides the atmosphere of music. For instance, when the tune is performed by distortion guitar and played with accompaniment in 8 beat, it will sound like rock music no matter what melody they play.
However, musical instruments and accompaniment are not the only factors that determines music style. For example, if you play the music of The Beetles by Okinawa Shamisen (Sanshin), it will not sound like Okinawa music. Therefore, the musical scale is what makes Okinawa music sounds like Okinawa music.
