The violin is a musical instrument of the string family, equipped with four strings tuned at fifth intervals. It is the smallest and most acute tool among the members of his family.
The instrument is similar to the violin, but about 15-20% larger and, unlike the latter, it does not have a standard size. It has four strings tuned for fifths, one fifth under the violin, compared to which it also has a deeper and less brilliant timbre; it is therefore an octave above the cello.
The cello is a musical instrument of the group of roped strings (bowed), belonging to the string family; it is equipped with four strings, tuned at right fifth intervals. They have 'F' cuts on the soundboard.
