I love the Karplus-Strong algorithm, it is a completely bullshit way to simulate a stringed instrument cheaply: https://en.wikipedia.org/wiki/Karplus–Strong_string_synthesis
It can be a bit tricky to tune that algorithm since in its simplest form it can only be tuned to integer divisions of the audio frequency. Using just intonation helps here!
The sample rate is 48000 Hz, and the "strings" are tuned to that divided by 54, 64, 72, 81 and 96, and then double those.
