The double bass – basis of harmony
The double bass is the lowest stringed instrument and also the biggest. Because of its height, the double bass is played at standing and it is, similar to the cello, supported by a spike. At the orchestra the double bass is an important basic instrument for harmony and rhythm. But it also finds use for jazz and in pop music. Decisive for the sound are the right double bass strings and the bass bow.
The violoncello – powerful and sensitive
The violoncello commands, as stringed instrument, the tenor- and bass region. Due to its tonal possibilities, reaching from powerful to sensitive, it is often used soloistic in the orchestra and has as solo instrument a rich selection of literature of cello notes. The tonal quality of the cello is, apart from the production by the violin-maker, above all characterized through the right choice of the cello strings and the cello bow.
The viola - inconspicuous, but indispensable
The viola is the alto-instrument of the violin-family. The viola is played with a viola bow and it is hold like the violin, with the aid of a shoulder rest and a chinrest. At an ensemble playing, like for example a string quartet, mostly forms a harmonic middle voice. As the viola musically rarely stands in the foreground, orchestras like to take the liberty of telling viola jokes.
