What's the difference between double bass and cello in appearance? How to distinguish?

The total length of cello is about 120 cm.

The height of double bass is about 180 ~ 220 cm, which is much larger than that of cello and almost as high as human.

Step 2 use string

The strings of a double bass are thicker than those of a cello (usually with a sleeve string).

Step 3 bow

The bow of the double bass is thicker than the cello and shorter than the cello.

3. Piano Shoulder

It was the double bass that "collapsed" (because its predecessor was the violin).

Like the violin and viola, the "round shoulder" is the cello.

Extended data:

The double bass has a fourth chord, and the four chords are E, A, D and G. In order to avoid adding too many lines to the bass spectrum, its sound is 1 octave lower than the actual notation. Sometimes a fifth string with a pitch of C is added, or a mechanical device is added to the neck of the piano to lengthen the E string, so that the following C sound can be played.

Cello has four strings, the range is about four octaves, and the pitch is eight octaves lower than that of Viola (C-G-D-A). Music scores are usually based on bass spectrum, sometimes using midrange spectrum in high-pitched areas, and sometimes using high-pitched spectrum. The first A string of cello is gorgeous and powerful, full of singing, the second D string is hazy, and the third and fourth strings (G, C) are deep and loud, which can bear the very heavy sound of the band.
