lexus21, you must understand that posting a claim like yours is going to be met with a great deal of scepticism. It's like an apprentice woodcarver claiming he has produced a piece of furniture as well made as a Chippendale, or a chess player who has been learning the game for 8 months saying he can play like a grandmaster.
I'm not saying it's impossible, there are famous instances of great talent emerging at a relatively early age, but these are very rare.
The G minor Ballade is something that many, many pianists aspire to play, and many never get there.
So yes, there will be scepticism on this forum from some very good pianists who have a real appreciation of the challenges that this piece presents.
Please prove us all wrong! It shouldn't be that hard to find a mic and make a recording, there are tutorials on YouTube that can help you make an accurate one.
And if you do, brace yourself for some of the criticism of your playing that will probably come your way. Don't take it too much to heart. If you can play this piece even tolerably well at the age of 13 and after only 8 months at the piano, you will have a great future.
