Looks like a previous version was mostly a Clojure DSL, but the latest major version no longer is. There are variables and other useful features we know from other programming languages that aren't mentioned on the landing page.
Of course there are also varying definitions of what a programming language is. For instance, I consider CSS to be a programming language, but I know many people disagree with that position (and that's okay). I personally don't think that a "programming language" must be a general-purpose, turing-complete language. Alda seems to be a non-general purpose, turing-incomplete language. At this point though, we're maybe getting into semantics a bit.
