Final answer:
A classic tango orchestra typically includes the bandoneón, violin, piano, and double bass, which together create the quintessential tango sound.
Step-by-step explanation:
In a classic tango orchestra, you might typically find the following four instruments:
- Bandoneón: A type of concertina particularly prevalent in South American tango music akin to the accordion, but with a distinct sound that is essential to the style of music.
- Violin: A string instrument played with a bow, contributes to the melody and richness of the tango music.
- Piano: A keyboard instrument that provides both harmony and rhythm to tango compositions.
- Double bass: A larger string instrument that supports the rhythm and adds depth to the overall sound of the ensemble.
These instruments combine to create the dramatic and passionate sound that tango is known for, with the bandoneón being especially synonymous with traditional tango music.
