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 contains numerous working Csound orchestras and even complete pieces. The examples/Boulanger_Examples directory contains hundreds of working Csound orchestras.

The doc/manual/html/indexframes.html file is the front page to the Csound Reference Manual.

This version of Csound is programmable in Python, Java, Lua, and LISP, and scores can be generated in these languages.

The doc/manual/api/index.html file is the front page to the C/C++ Csound and Csound API application programming interfaces reference, but it is also helpful when programming Csound in other languages.
