Technique and posture.

I haven't used a metronome for like 40 years except to check tempo. I had real old school teachers. I've always had an excellent sense of rhythm. It's something I was born with.

Metronomes are a tool that is sometimes needed to help a student develop a sense of rhythm. But I feel they can become a crutch because you can't always play with a click track, and overuse can make things too mechanical. IMO. And I refuse to play classical with a click track.

So to answer your question. No I don't practice with a metronome. I use it to check tempo. I play other instruments too. I play guitar, primarily rhythm, and work well with a drummer and bass player. when I'm working on a rock song where I have to play do some lead and solo work, I'll practice with a drum track.

ah gotcha, yeah i would imagine that it would be awkward to play classical with a metronome lol. we use clicks when playing just because we put loops in and have to stay on time for the light sequences that are preset but i usually only practice really tough parts and our clicks are always a drum track over a metronome. thanks!

I could just be crazy, but I listened to nothing but classical music for an entire month and it was very interesting to see the difference it made in the way I wrote and played. It sharpened me quite a bit.

what style do you typically play?

I usually describe my style as being prog. as an example http://soundcloud.com/mk-iv/on-the-outside

its one of my slower, more chill pieces.

ahhh gotcha

I would never say playing with a metronome is bad for practice but I would not that you also have to stop so you can do the part for real. Good example to recover speed from a car accident that I suffered some nerve/motor skill damage from, I practice Hannon starting at 68-108 (8 notes even between 2 clicks) and this can get pretty intense! The player should concentrate on stability and comfort along with ensure that there isnt that sense of close enough precise with no questions.
There are various note and finger combinations that focus on strength and independance. Also Isador Phillip has a rather intense technique book that forces you to be a "technically" Amazing player!

Classical postures go out the window at a gig because you are performing, but the need to practice what you do. I play Bostons Foreplay longtime with a few bands and I play it on a keytar just because its crazy lol I have to practice it all the time to maintain on the regular keys or organ as well as the keytar. Literally every 3 days i have to play that piece. Metronome helps the discipline with the fast triplets.

The fingers should do the walking not the arms. So when your playing dont dig it from the shoulder use your fingers. This is where those excercises come in. Even if I'm trying to "Sell a part" and jump up in the air and Strike the keys like thor just before I hit I play from the fingers not slamming and smashing the keys(kinda like wrestling with a big wind up and a soft chop) Syncapation excercises are crucial as well especially in the funk/R n B/ Jazz world

Correct hand and sitting position as well as wrist and elbow movements have to reflect music idea, it's relief and stay in harmony with it. That's it))
