1, scale practice.
A scale is a natural arrangement of tone levels of one or several octaves from tonic to tonic. From the mode point of view, scales can be divided into natural major and minor, harmony major and melody major and minor. Like other playing techniques, scales are played in two ways: Legato and Legato. Legato of scales mainly acts on the joints of fingers and palms, and it works through the flexible lifting of fingers and palms.
The supporting point of force is on the fingertip and metacarpal joint, which is characterized by fast key pressing, concentrated force points, strong explosive force, quick key separation, flexible action, transparent timbre and strong graininess. A diatonic Legato is the first sound made by putting down your finger. It is convenient to transfer the weight to the following sound stream. After the big finger is in place in advance, a new hand shape should be formed immediately. It's best to practice scales slowly first.
2, arpeggio practice.
Arpa is also called broken chord, which means that chords are played from high to low or from low to high. Generally speaking, no matter what form of arpeggio is played, you must use your thumb and two fingers. Only when the third and fourth notes are four degrees apart, the third note uses three fingers. If the third tone is three degrees apart from the fourth tone, the third tone must use four fingers.
3. Chord practice.
Three or more different sounds are combined together according to certain rules, and the chords are pronounced at the same time. When playing chords, pay attention to the neat sound of touching keys. Remember, uneven playing results are caused by different lengths and strengths of fingers. When playing, keep your wrist parallel to your thumb. Do not hesitate to press the key to ensure the brightness of the chord timbre.
