Wilifried, you surely have the right recipe!

There are a couple of hitches to the adult student of complete music-craft. Nothing could be more un-intuitive than bowing a Violin, and nothing can equal the complications of playing two handed on Piano or similar. Wind family instruments require lots of planning but practice and time take care of most problems. ( I have mastered, even if badly, both home made Diatonic flutes and the pennywhistle. I must add, there is absolutely nothing that gives so much reward as playing a musical instrument you make! )

It is always a good rule of thumb to begin with some lessons. Later you can go off on your own, but to start nothing so well corrects time wasting mistakes in method as a teacher.
