Well thanx for the explaination about Jazz fusion. So, it is the combination of jazz with any kind of music style. You do help me to understand but of course not very clear but at least I roughly know the concept already. Basically, I can play any kind of concept or form of scales and technique but when it comes to this as my friend mentioned this to me, I think I better have a try on it as this may be a new concept I have to learn and analyse the sound, tones and techniques. Thanks again Willdridge. I really appreciate it.
