Practising scales intelligently

Playing scales while thinking about your shopping list is almost useless. Scales become a superb tool as soon as you give each repetition a precise aim: evenness, tone, an invisible thumb, speed, dynamics. Here is the routine I suggest to my students, to adapt to the time you have (10 minutes is enough).

1. Sound first, slowly

One octave, hands separately, crotchet (quarter note) = 60, one note per beat. Each note is placed with the arm's weight. Listen: do the eight notes have exactly the same volume? Can you hear the thumb more?

2. Rhythmic variants

Dotted rhythms force each finger to be fast one moment and "leaning" the next. They reveal and correct unevenness far better than identical repetition. Play each variant twice, then return to the even rhythm: it will suddenly feel easier.

M:4/4
L:1/8
Q:1/4=60
K:C
C>DE>F G>AB>c | c>BA>G F>ED>C | C
Variant in groups of three (triplets): the accent falls on different fingers each time, which breaks lazy habits.

L:1/8
Q:1/4=60

(3CDE (3FGA (3Bcd (3efg | (3fed (3cBA (3GFE D2 | C8 |]

3. Stopping on the thumb (stop-and-go)
Play each group of fingers quickly (1-2-3, then 1-2-3-4), and stop on the next thumb, already preparing the hand. This teaches you to play fast in small relaxed bursts, instead of laboriously speeding up the whole thing.
4. The different forms

Parallel motion an octave apart, then a third and a sixth apart (left hand starting on the tonic, right hand on the mediant or submediant).
Contrary motion: both hands start on the same note and move apart. The fingerings often coincide, which is very instructive.
Several octaves: two, then four, moving your torso with the line.
Dynamics: crescendo going up, diminuendo coming down, then the reverse (much harder!).
Articulations: one hand legato, the other staccato.

5. The metronome ladder
Once the scale is secure at 60, raise the metronome 4 notches at a time. As soon as a mistake or tension appears, drop back two notches and play it three times perfectly. Write down your "comfortable" tempo in a notebook each day: progress is often slow but steady.

Common mistakes:
Always playing at top speed: you consolidate the flaws.
Only working on C major: go round the circle of fifths.
Forgetting the music: a scale can (and should) be beautiful.
Tip: pair each scale with a piece in the same key. Working on G major before the Minuet in G gives the exercise a concrete purpose.
