I've been playing all sorts of styles of guitar for nine years now, and I have a good understanding of theory. I recently started playing the piano as well - specifically more towards the jazz side of things, but I'm happy to learn some classical as well. I started playing about a month ago, but I'm having trouble learning the theory and technique side of things.
I find it difficult (and a bit boring) learning scales and simple chord voicings (triads, seventh chords) since I'm so used to the sound from playing guitar. It's difficult to motivate myself learning theory and technique on the piano because of this. I have a copy of Oscar Beringer's Daily Technical Studies for the Piano, and I've been working through that, since the exercises are a bit more interesting, but even still, I find it quite hard to practice these for more than ten minutes a day.
I could be wrong, but it seems to me that it's unnecessary to practice easier techniques like this when I have already played guitar for this long. (I understand it's important to develop good technique, but will it not come naturally as I practice more complex things?)
So my question is this, is it necessary to practice triads, and seventh chords etc. or can I move straight on to upper structures and drop 2 voicings etc, and start learning some standards? If people think it's important to practice technique, does anyone know of some more interesting things to practice?
Cheers
