Releasing tension is a huge subject that is often not discussed in lessons. Every situation with tension is different, just as our bodies and mannerisms are, but there are also common trends that appear in a number of players.
Releasing tension whilst playing is something unconscious for many players who don't realise they are doing it, it is just a natural part of playing. Generally speaking, the release of tension whilst you are playing is done in the wrists - it is important not to have static wrists and to allow them to ebb and flow. Everytime you move a finger, muscles are tensing then releasing in the up and down action. The same is true of your writst, although it is more common here not to do the releasing!
If you think about it terms of music - in traditional harmonic patterns, there are tension points and release points (Bach's 2nd Prelude from WTK Bk 1 is a prime example!). So it is with your wrist - if there is a tension point when your wrists may tighten up for a particular movement, then there should be a release point created to negate the tension in the previous movement - does that make sense?
Somtimes tension is due to a lack of finger strength or a weak hand position. When you are playing more complex/difficult pieces where your fingers have to do more work and you have weak fingers, your wrists and arms will start to compensate by tensing up to 'take the strain'. In cases like this, it can often be a long time before the cause of the tension is discovered. The main reason is because, if I for example asked someone with wrist tension caused by weak fingers to change their hand position so that their fingers did the work instead of the arm, they would find it very difficult to play as the fingers are not used to this! You would have to start seriously focusing on uilding strength, which is hard and needs discipline, so it is often simpler and easier for the player to continue as they were before. People with this problem tend to find that they "can't play" certain pieces that are within their level, and this is frequently put down to the piece "not suiting their hand shape" or some nonsense like that. This can lead to people reaching a point where they can't progress any further after a while, which is sad, because if time was taken to correct the problem, a whole new world of music would be opened to them!
Tension can also be caused by tension in the back and shoulders, which may be a result of a not-optimal sitting position. Tension in this area can also be due to stress or anxiety completely unrelated to your playing, such as a family problem, money worries, etc, which is where general relaxation and things like the Alexander Technique and Yoga come in - It is unbelieveably important for musicians to understand the importance of the effect of thier lives on their music and to create a balance in their minds and bodies so that their playing might also be in balance. The way we play and express ourselves on our instrument is so integrally linked to our inner being.
There are a number of things you can do to check whether you are releasing tension and to remedy it, although it is a huge subject and for a tension problem, it involves being aware of your playing and may take a couple of practice sessions to resolve, or several months.
As one example: sit at the piano, shake your arms out at your sides, take a few deep breaths and relax your shoulders and arms. There is a good sitting sequence that you can try to begin with that really helps with aligning your body in a relaxed, yet focused and alert position, which also helps relieve tension:
- sit at the piano in your normal position
- place your feet square on the floor, about hip width apart
- lift up your toes, keeping your heels on the floor, then lay them down slowly - 1 at a time if you can (works best with shoes off!)
- lift your heels, keeping your toes on the floor, then place them down and slightly back, establishing a firm grounding
- tighten/draw in your abdominal muscles slightly - this supports your spine and can help you feel more alert (I don't know if you like yoga, but it is believed that the stomach can be the centre of the body's energy)
- roll your shoulders forward, then back, placing them back and slightly down - not too much than is comfortable though!
- stretch your arms down at your sides, armpits slightly open, palms facing outwards - reach through your fingertips to the floor
- turn your hands so that your hands are facing frontwards, reaching down and feeling a warm stretch in your arms
- after this, take a few deeps breaths and feel more centred and relaxed
This is a basic exercise to begin with, which can help instil a calm and focus in you. After this, you can try an exercise to promote flexibility in the wrists, which I mentioned on another thread about wrist flexibility
here a while ago.
It goes like this and is so so beneficial to anybody:
- Place your fingers on E, F#, G#, A# & C. (or I guess F, F#, G# A#, B might be better if you have small hands)
- Press the notes down (gently - don't use much force, just enough to make them go down)
- Now rotate your wrists slowly a few times in 1 direction, aiming for full circles rather than side to side motion, which is what tends to happen when you have inflexible wrists.
- Then do the same with the other hand.
- Lastly, do both hands again, but in the opposite directions to the first time.
Really try to make ths circles as large as you can, making your wrist sink deep below the keys. If you can make big circles, don't worry - that is what this exercise helps you do - just start with what you can and aim to gradually increase the distances. Try also to lead with the bone on your wrist (the little bump that sticks out slightly).
If you do this a couple of times each day (not too much and not strain yourself) you'll find that your wrist flexibility gets better.
Sorry for such a long post, but tension release is so important! Piano playing should be like wearing an onld pair of slippers that are so comfortable you hardly feel you are wearing them - by this I mean that you should not feel uncomfortable whilst playing, every movement should be easy and fluid. Now of course this is simple to say and not always so simple to do, but that is part of the learning process of the instrument!
