Unable to install this package on emacs 29.4

[Ian-Grant]

It does not appear on the Mx package-list-packages list. It does appear on melpa.org, but requires emacs 25, maybe that's the reason MELPA doesn't offer it? I also tried adding the lines below to my ~/.emacs but I get an error "Debugger entered--Lisp error: (file-missing "Cannot open load file" "No such file or directory" "dash") If I install dash I get errors "File is missing: Cannot open load file, No such file or directory, multi" and lots of "⛔ Warning (comp): dash.el:615:2: Warning: docstring wider than 80 characters"

(add-to-list 'load-path "~/.emacs.d/csound-mode-20240823.857/")
(require 'csound-mode)
