The viola is a member of the string family of instruments. Its relatives are the violin, the bass, the cello, and the double bass. There are other string family members, but they are not as closely related to the viola, such as the harp and the piano.
Double Bass. (The Piccolo is- I believe- the highest sounding member of the woodwind family of standard orchestral instruments whilst the Double Bass is the lowest sounding member of the String family).
That would be the bass violin also known as the double bass
The instruments are vocals, Bass Guitar, and drums
The double bass is said to belong to the violin family, and in general, wide terms, this is so. However, the viola and double bass have much more in common than either have with the violin, and if you find a recording of the bass being played in its highest ranges, it is easy to mistake it for a viola. So for general purposes, it can be said that the double bass is a member of the violin family, but it is really a member of the viola family.
in a string orchestra the instruments are: Bass Violin Viola Cello.
Most instruments are pianos, drums, bass, & viola.
There are a wide variety of instruments which are capable of playing bass. Some examples include the guitar, piano, keyboard, trombone, tuba, baritone, and bass clarinet.
bongos, piano and bass
drums
The Double Bass is a string instrument. Other instruments in the orchestral family of string instruments are the violin, viola and cello.
I don't believe there's any such thing. The double bass is the lowest-sounding and largest member of the orchestral bowed string family of instruments. Please forget trying to define it otherwise- does it really matter?
