Install with Homebrew returns with "No available formula with the name "fluidsynth""

[Ranger6012]

I am trying to install fluidsynth using the Homebrew command provided here (brew install fluidsynth). However, using it returns with this

Warning: No available formula with the name "fluidsynth".
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
==> Searching for a previously deleted formula (in the last month)...
Error: No previously deleted formula found.
==> Searching taps on GitHub...
Error: No formulae found in taps

How do I fix this and install fluidsynth, Homebrew is installed correctly. I am not sure if this is the case for everything as I only intended to install fluidsynth.

For some reason, Homebrew calls it fluid-synth: https://formulae.brew.sh/formula/fluid-synth#default

Trying brew install fluid-synth returns with the same response of no available formula
