Theøry Frøg is an website that can help you with music theory! you can query it and it will generate information for you.
Type in a list of comma separated notes. Is not case sensitive.
For sharp and flats, use #
, b
, ♯
and ♭
.
Examples: C#,D#,E#
, f,a,c,e
, bb,db,fb
.
It will generate(if named) inversions(rotation of a chord), subchords(subsequence of a chord), chordtone wholetone scale(a way to build a scale from a tetrad), strict chordscales(where the chordtones are on uneven scale degrees), supersequences(scales such that the notes appear in it in order and uninterrupted) and supersets(scales such that the notes are all present in it).

Theøry Frøg is a simple front-end web app, without backend. It's made with simple HTML, CSS, JS, and WASM. A Rust library does the actual calculations, which is imported into this theory-frog rust crate (https://github.com/codybloemhard/music-theory). The theory-frog rust lib is than compiled to WASM and used.
