Such is the essence of analog sine wave generators. ~70 years ago, HP started with a tube circuit that was one such, and used an incandescent lamp for automatic gain control. HP Virtual Museum: Model 200A audio oscillator, 1939 HistoryP
Sine Wave Oscillator using LM741 - Engineers Garage

The circuit will generate sine wave output when op-amp gain is adjusted to slightly more than 29. Now op-amp gain is A = -R1 / R5 But R5 = 1 K and R1 is pot of 47 K. So by tuning pot R1 we can adjust A as greater or equal to 29 to generate sustained oscillation of constant amplitude. The circuit oscillates at a frequency F = 1 / 2πRC√6

A sine wave generator is a circuit which can generate sine waves. This is the type of waveform that comes out of household electricity outlets. This is the waveform that you see in AC power. Sine waves are also used a lot in acoustics. All different types of waveforms produce different sounds, so sine waves is one of many that are used in acoustics.

oscillator yields four sine waves 45° phase shifted relative to each other. This oscillator can be used to obtain sine/cosine or quadrature sine waves. Crystal or ceramic resonators make the most stable oscillators because resonators have an extremely high dφ/dω as a result of their nonlinear properties. Resonators are used for

This oscillator works with any standard 9Volt wall adapter, commonly used for guitar pedals, shown in the pictures below. Simply plug it in to the 9V jack, take a standard 1/4" cable, plug it in to some speakers, and you're ready to make weird noises!
Using LM386 As an Oscillator. : 5 Steps - Instructables
https://www.instructables.com/Using-LM386-as-an-Oscillator/
Using LM386 As an Oscillator.: Most people know the LM386 as a mono amplifier. What may surprise some people is that the LM386 can also be easily converted into an oscillator without any other specific IC's like the common 555 timer chip. In this Instructable, I'm going …

Distortion analyzers inject a low distortion sine wave into the input of the DUT and then extract that signal somewhere downstream from that point. The signal is fed into a very sharp notch filter to null out only the original sine wave frequency. Anything that remains is distortion products; noise and hum that were created in the DUT.
