CsoundQt, a graphical shell for Csound, makes an excellent place to begin the exploration of Csound, especially because CsoundQt has an extensive menu of built-in examples that show off Csound's capabilities. Many musicians make CsoundQt their main Csound environment, although there are other excellent environments. CsoundQt runs not only Csound code, but also Python scripts.

The examples directory and its subdirectories contains numerous working Csound orchestras and even complete pieces.

The Csound Reference Manual may be found online at, or it may be installed with Csound in a location that varies by operating system.

This version of Csound is programmable in C, C++, JavaScript, Python, Java, Lua, and Common Lisp, and scores can be generated in these languages.

The Csound API application programming interfaces reference may be found online at, or it may be installed with Csound in a location that varies by operating system. The API reference is generated from and for the C and C++ API, but it is also helpful when programming Csound in other languages.
