Tony, first, you CAN play in all 12 keys which is excellent. You can obviously hear the ii-V-I progression which is foundational to playing over tunes. I don't think it's fair of you to say you have no language. If that were true you couldn't play the phrases you played.

You wrote, "Too slow." I'm not sure what you mean by that, but perhaps you are referring to your need to hear the chord played before launching into a phrase-you are reacting to the changes slowly? And you would be right. The chord sequence is predictable - moving up by fourths - so the trick is to hear and anticipate the pattern without having to hear the chords/key first. This will help you play better on tunes, where your ear leads you through the changes. I call this harmonic anticipation. I'll link to an ebook with exercises for this.

Try this: play the rhythm track and sing phrases. Do your best not to wait for the ii chord, but instead, hear that predictable modulation and sing one phrase smoothly leading into the next. It really is a matter of hearing that transition. Remember, you can't play what you don't hear.

I linked to a track of me playing the first four cycles as an example of playing melodically from one key to the next. Nothing fancy, just smooth transitions. This is not to "play like Mike" but hearing an example is clearer than me just writing about it.

I think you have a very solid foundation. Your next step is to train your ear to HEAR and anticipate the upcoming changes and the modulation. I look forward to hearing the result of your practicing that!! Keep up the great work!
