IMHO improvisation skill are developed with hard work and good instruction.The videos that I put up over the last few days show different skill sets. I don't think there is a magic position that solves all of the problems of playing over changes. A tune like The Girl From Ipanema goes through at least 8 tonal centers. A knowledge of chord changes would be helpful to say the least. Without good tone getting the listener in to hear what your playing will be difficult. There is no magic bullet microphone that's gonna change that. The ability to move around the harmonica is essential to help you get the full of expression of what you want say in your solo. All of this combined with natural talent and good ear seems to be good recipe.
This piece was recorded live in the studio. The harmonica part is improvised.It was done in two takes. NO OVERDUBS
I told them I was gonna make the harmonica sound like a cello. No special effects were used. There is only reverb. I used an Akg c414 mic.
