Final answer:
Stringed instruments are expressive with varied tones due to their design and playability, while wind instruments' expressiveness stems from their connection to a player's breath control.
Step-by-step explanation:
The central ideas of the text are that stringed instruments are particularly expressive due to their range of sounds and playability, whereas wind instruments have a unique expressiveness because they are closely connected to the player's breath and bodily control. Stringed instruments, like violins, violas, cellos, and double basses, produce sound through the vibration of strings, which is resonated and amplified by the instrument's sounding box, allowing for a rich variety of tones and overtones. This is contrasted with wind instruments, which use resonating air columns that are controlled through the musician's lips or a set of vibrating reeds, resulting in a personal and finely controllable sound.
