When it comes to finding a good piano teacher, convenience and quality rarely go together.
If the main criteria for teacher selection is the one with an opening on Wednesdays at 4:30pm, then you're prioritizing convenience. And the odds are slim that a quality teacher will have your exact time slot of preference available.
Same if you're looking for an in-home piano teacher, saving the commute time.
There's nothing wrong with in-home piano lessons in theory.
But, the reality is, the market is flooded with sub-standard piano teachers who travel to students' homes. (Not to mention, most don't realize they're supposed to have liability insurance.)
The tough part is, your average parent or adult student doesn't know the difference between convenient and quality.
So, the convenient option appears to be the best option.
When quality is prioritized, it doesn't necessarily mean inconvenient.
You'll probably have to give a little.
But you'll get a lot in return.
