First of all, you should practice scales and arpeggios well, at least within two octaves. Because scale arpeggio is an introductory textbook for training tonality and rhythm uniformity, and a successful fast bow must be based on these two.

Second, practice fast bow should take the middle bow or the upper half bow, do not use the lower half bow, nor can you use the bow root.

Third, start with a slow and long opening, the volume should not be too loud, and the version should keep the sound clear and the beat balanced. Then go to Allegro and Allegro Shortbow.

Fourth, with the speed gradually accelerating, the right hand gradually moves from the arm to the wrist, generally without the action of the big arm (upper arm), through the interaction between the forearm and the wrist.

Basic common sense

1, know the violin

There are four strings in all. Rub the string with a bow to make a sound. The piano body (resonance box) is about 35.5 cm long and consists of a curved panel, a back panel and a side panel. Panels are usually made of soft spruce; The back plate and side plate are made of maple and peach, which are hard. The head and neck of the piano are all maple, and the fingerboard is ebony.

Step 2 hold the bow

The thumb and middle finger of the right hand are bent into a ring, and the thumb is bent upward. Don't squeeze it or use force. The index finger hooks the silver coil of the bow slightly inward, and the little finger is relaxed and supported on the bow in a slightly curved shape, which makes the bow more stable when playing. Except the thumb down, the other four fingers should be at the same distance on the bow, so you can easily put the force on the bow.
