airborne_artist probably made the most important point here :
Age, lesson frequency, instructor
Lesson frequency is of paramount importance. If lessons are once a month, or even less, the one spends at least a third of the next lesson catching up on what has been forgotten since. If lessons are much more frequent, say once a week, or even more, then much more reinforcement of acquired skills can occur.
In many, especially the young, lesson frequency is solely dependant on what can be afforded ! So, as always, finance comes into it !
My own first solo was 26 years ago, but I'll keep the hours to myself !
