"ONE OF the biggest challenges to traditional music learning is the need for practice. Students must play scales, chords and patterns over and over in hopes of developing muscle memory; for many, it is a daunting and tedious task. Research has shown that individual practice is often not productive because learners receive limited feedback and too often lose interest and motivation." from http://www.economist.com/blogs/prospero/2017/03/casual-learner-era The article then goes on to discuss various "apps" for salvation. Have a look yourself, though I'm not convinced.
Let me address the issue.
If you are having some difficulties finding "time" or motivation to practice, I've some suggestions.
Maybe. But is that the point? Are music lessons taken and given for instrumental reasons only?
Playing music has its own rewards.
On the other hand.
Learning to play an instrument over a number of years instills though experience and a number of instrumental values that benefit children as they progress towards adulthood.
You've got to learn your instrument. Then, you practice, practice, practice. And then, when you finally get up there on the bandstand, forget all that and just wail.
