Welcome to Gaia! ::

Actually I am going to tell you what my paino teacher keeps telling me, it is all about how you approach the piano. I am more of a vocalist and euphonium player, but I have to play piano juries for my degree. I know that the more I put the emotion into my fingers the more expressive it sounds. Like in really intense parts, press the keys harder, not necessarily for the dynamic, but rather the richer, darker sound of the string that is being struck by the hammer. If you get stiff take a deep breathe and press on. Everyone in music has a tendency to tense a muscle in there body when they get nerveous, the question is what you do to get rid of it. A really ideal and good possiblity for piano and stiff arms is to over dramatisize (I suck at spelling...) a reach. Like if there is a big leap in hand position lift your whole arm to release that tension, and give your listeners something to look at. Good luck!

There are times when I actually love performing. Just keep in mind that it's normal to be nervous or anxious. What you need to realize is that it's just another type of adrenaline. Take advantage of that extra energy and incorporate it into the music. When you have long rests or long pedaled chords, clamp the muscle that's stiff and then relax it. For expression, sometimes in the more climatic moments, I lean in towards the piano. It gives off a much darker and intimate sound to your ears. At the same time it encourages you to continue to make that sound. If it helps, you can always look up the music on youtube to guide you for the expression and such.

Usually when I play, at first I focus very very carefully on the music but after awhile it's just natural. Then you're able to just enjoy the music.
