Everything you do, sounds. All your movements, both intended and unintended, have their effect on the sound you produce

Alan Fraser

Technique lies at the foundation of piano playing, and good technique can serve the beginner student right through to advanced level. However, it should never be the “be all and end all”. Rather, it should serve the music – to create when required, for example, the lightest staccato, the most cantabile melodic line, a bubbling Alberti bass, sprightly trills and tremolandos, the most fluid legato.

Pianists are often praised for having “fine technique” or “superb technique”: this can range from obvious things such as physical agility/velocity and stamina to more esoteric, “hidden” aspects such as arm weight, wrist rotation, and alignment. These days, with the prevalence amongst mostly oriental generic pianists for putting technique above all else, piano “technique” has come to mean sheer physical capability, speed and sound production (usually too loud!) without a true understanding of how a particular technique specifically relates to the music, and the effects the composer is asking for.

Perhaps the most obvious example of this is staccato, of which there are different kinds:

• Arm staccato gives equal measure to each note and is particularly useful for a crisp, short or bouncy sound. Involve the forearm and keep the wrist soft. Avoid pure wrist staccato as this pulls up the fingers and creates tension. Aim for a free drop of the arm and then bounce off the keyboard on the rebound.
• Jeu Perlé literally “pearly playing”, this is particularly useful for semi-quaver passage work in Mozart and the like, also in Debussy, where such passages should be played quickly, lightly and clearly, and where too much obvious articulation would create dryness. It is a type of staccato playing that creates the tiniest sense of separation between each note (like the knots between the pearls in a necklace), and requires small movements and a close attack. Play the note and let it bounce up at you – i.e. do not pick the fingers up.
• Finger staccato/flicking staccato Possibly the hardest staccato technique to perfect, this requires the fingers to flick off the keys and back towards the palm of the hand. Beware of tension in the hand and wrist when practising this technique, and employ the alignment of arm and wrists to fingers. To play repeated notes with finger staccato, practice using different fingers (say 1,2,3,4) but allowing the wrist and arm to take the fingers into position with a “polishing” movement in the wrist (I imagine there is a tiny pencil under my wrist, drawing an ellipse shape).

A pianist who has done their homework, and has fully studied, understood and absorbed the composer’s intentions and instructions in the score, will know what kind of staccato technique to employ for a particular section or passage.

When starting out with any new aspect of technique, whether teaching it or doing it for yourself, it helps to enlarge the movement. Thus, when I am teaching rotary movement, I get the student to make the movement in a broad brush away from the piano. I like to use the image of windscreen wipers for this – a visual cue which children find particularly easy to understand. Also, one is trying to suggest an ‘outwards-inwards’ movement rather than the reverse. Never attempt to teach a technique you have not learnt and understood yourself first.

Don’t practice technique in isolation, but rather understand how it should be employed in your music and then make a technical exercise out of a small passage or section from that music. Doing exercises like those by Czerny or Hanon are, in my view, less worthwhile than a technical exercise you have devised yourself to practice a particular aspect of your repertoire; it is also more interesting! Having said that, I have found Brahms’s ’51 Piano Exercises’ helpful, and also tuneful to play.
