I play the piano, mostly jazz but I dabble in other venues if there is something i like alot.
I consider it another layer of "my onion"; part of something a woman has to peel to find out more about me. Makes you more interesting. Women Love to peel away layers of you, you just have to let them. the Piano in itself won't get you laid, but it can make you more intriguing which CAN get you laid. I mean, I have been playing for 17 years now, I dont' do it for women, I love the piano, but at the same time it's something else that adds some mistique to you.
I dont' come out and say "hey woman look at me play this song, you must lay me now, or look how cool I am". I let women find out I play the piano. and I d on't so much let them find out as much as eventually you will catch me playing the piano.
I remember when I first met my fiancee, I have a piano in my house and she asked could I play it. I told her I messed around with it and left it at that. There is a song that I found out over time she LOVES (But Beautiful - Jimmy Van Heusen) that I play quite well, but I never told her. On her birthday after dinner I played it on the piano for her. Talk about melting a heart. I literartly sat there and watched her melt, great night that night.
Used tactfully, playing the piano like anything else, can be a part of a good arsenel.
I remember one time when I was 21, I went to a piano bar and they were having open mic night, and after a few drinks I said fvck it, and went up there and played a few songs, Bennie and the Jets and And I am telling you by Jennifer holiday.. I got laid that night too by a woman I met that night.
