Sure, but even though we consider Jazz anything that sounds jazzy, i.e. using Major 7ths or flat 5s, because Jazz and Classical are so individually encompassing, literally every other genre of music is also Jazz and Classical, any sound that can be made with an instrument fits in Jazz and Classical, i.e. it can be interpreted using the modes and forms of Jazz or Classical without changing how it sounds. It just isn't very useful to approach or interpret, say, a folk song from the perspective of Jazz, nor the sound a guitar makes when smashed to pieces, but technically, everything is either Jazz or Classical or both.
