I hope you have not missed my message?  To take lessons to learn the piano isn’t very easy.  It is even more tricky if you’re an adult newbie.  Make no mistake ; it truly does need a great deal of understanding, tough work, and practice.  I would even say that it may never be fully mastered. 
 
If you are a musician who is always seeking to learn new things, then learning to play by ear is a suitable challenge.  I’m hoping you first read the learn piano with hear and play review before settling on a course to study. 
 
Other musical challenges can be learning a totally new chord progression, advanced music theory, or perhaps exploring some different music styles.  There’s always scope for progress and discovery!  Remember the hear and play review could be just what you want to set you on the trail to a completely new musical experience. 
 
I’m not sure about you, but if you are anything at all like me then you struggle to learn music theory.  All those things like how chords are formed, the way to write a tune, and the way to harmonise a tune.  You don’t know ways to exploit music theory to your benefit.  Let me make you think about the review of learn piano with hear and play if you are considering learning to play piano by ear. 
 
During the past, you most probably wrestled with other self-help books and’how-to’ videos without success.  The same goes for music training manuals too.  Do not allow that experience put you off as I know you will not be disappointed.
