Final answer:
The composition "Up with the Lark" by Bill Evans utilizes piano and double bass/bass fiddle, utilizing the principle of resonance within the piano strings and soundboard, and the double bass strings and body for sound amplification.
Step-by-step explanation:
The instruments used in Bill Evans' composition "Up with the Lark" are piano and double bass/bass fiddle. In the context of Evans' typical jazz trio setting, the double bass forms the foundation of the harmony and rhythm, while the piano provides the main harmonic and melodic content.
Both instruments use the principle of resonance to amplify their sound: the piano through its strings and soundboard, and the double bass through its strings and hollow body.
String instruments such as violins, which are not part of this composition, create sound by vibrating strings, which is then amplified by the instrument's body.
Similarly, the piano also has strings that resonate within the soundboard to produce its distinct tone. The double bass, being a larger string instrument, operates on the same principle but with deeper resonances due to its size.
