The viola has rich and full tone color, has bright character, is good at playing melodies for expressing deep and complicated feelings, also has a bass part which is commonly used for harmony with the viola and is called as "noble woman of music". Cellophane was originally spelled in italy as Violoncello, and was later gradually abbreviated as Cello. Cellos are known for their hot and rich timbre and are one of the most common musical instruments in symphony bands. Is suitable for playing various roles, namely adding bass camp sometimes and giving a heavy sigh at a bass part; sometimes the middle two chords play a role in the rigidity of the rhythm. At the moment of the cello being the most brilliant, the musician must be counted to give the musician the mission of expressing the melody like a song. The wonderful melody played by the whole violoncello group is enough to dwarf any other musical instrument in the symphony band.
