Something I'm constantly faced with is the question "Is it easier to learn piano at a later age in life?" or "Am I weird for starting lessons now that I'm 24 (or 30 or 50)???" Well, let me start off by saying that it's never too late to learn! Piano is such a joy that if you have the time, don't let anything stop you from learning! Secondly, I've taught people as young as 5 and as old as 50. In fact, I currently have a few brand new students that are in their 20s, so you're definitely not alone!
Younger students are faced with certain challenges that older students have long since overcome:
-distinguishing left hand from right hand
-basic arithmetic, fractions
-alphabet
-attention span
On the other hand, younger students tend to soak new concepts up like a sponge, and they have yet to learn the discipline to practice regularly on their own. Older students have their own challenges, though:
-managing lesson/practice times around work
-sticking with it past the basics
One attitude that seems to be common with older students is they think that since they're older they can take a few lessons and then learn the rest on their own. Don't make this mistake! Learning piano, or any other instrument for that matter, is like learning a new language! You will get the most out of your experience if you 1) practice daily, 2) take lessons, and 3) play in recitals.
Thanks for reading! Leave me a comment, I'm always interested in what you think!
