Because the strings are longer and thicker which makes the frequency lower, which makes the note lower.
The Double Bass or the Contrabass is the lowest member of the string family.
It is the lowest member of the String Family.
The lowest notes in the string section come from the double bass.
The lowest sounding instrument in the ORCHESTRAL string family is the double bass. It is also the largest. Hope I helped. :D
The cello makes the lowest sound of a string instrument.
The lowest string on a four string double bass is an E string. If you have a fairly rare five string double bass then the lowest fifth string is a B string.
Violin, Viola, Cello then Double Bass
It is the lowest member of the String Family.
The double bass is called so because it is the largest and lowest-pitched instrument in the string family, providing a "double" or deeper bass sound compared to other string instruments.
The smallest and highest pitched member of the string family in modern times is the violin. The Eucolale and mandolin are also pretty small but in terms of pitch it has to be the violin. In the old days they was an instrument called a rebec which was like a violin but smaller. The rebec was very popular with soldiers as could easily be carried in their packs.
I believe the lowest is the double bass (the large looking "cello" you need to stand to play) because of its volume, thick strings and long strings.
The members of the string family, from the highest to the lowest, are the violin, the viola, cello and bass. Without the strings you would no longer have an orchestra, you would have a band, The string family, as a unit, can play the very highest notes and the very lowest.
