 The simplest way is to create a .wav file and have your system play that.

 There are also some other musical samples, twinkle.abc and menuet.abc.

 ### Remarks
 
 This is a sound synthesizer for a subset of [ABC music notation](http://en.wikipedia.org/wiki/ABC_notation).
 
 Try:
 
-    gcc -o prog prog.c
-    echo "CDEFGABc" | ./prog > /dev/dsp
+```sh
+cc -o endoh3 endoh3.c
+echo "CDEFGABc" | ./endoh3 > /dev/dsp
+```
 
 If `/dev/dsp` is not available on your system, use an OSS sound wrapper such
 as `padsp` or `aoss`:
 
-    echo "CDEFGABc" | ./prog | padsp tee /dev/dsp > /dev/null
+```sh
+echo "CDEFGABc" | ./endoh3 | padsp tee /dev/dsp > /dev/null
+```
 
 If you are using Mac OS X, try [sox](http://sox.sourceforge.net/):
 
-    echo "CDEFGABc" | ./prog | sox -q -traw -r8000 -b8 -e unsigned-integer - -tcoreaudio
+```sh
+echo "CDEFGABc" | ./endoh3 | sox -q -traw -r8000 -b8 -e unsigned-integer - -tcoreaudio
+```
 
 If they do not work, use the attached script to convert the output
 into a wave file format:
 
-    echo "CDEFGABc" | ./prog | ruby wavify.rb > cde.wav
+```sh
+echo "CDEFGABc" | ./endoh3 | ruby wavify.rb > cde.wav
+```
 
 and play `cde.wav`.
 
 You can enjoy some music scores that I attached:
 
-    cat twinkle.abc | ./prog > /dev/dsp
-    cat menuet.abc | ./prog > /dev/dsp
+```sh
+cat twinkle.abc | ./endoh3 > /dev/dsp
+cat menuet.abc | ./endoh3 > /dev/dsp
+```

 - How does it convert ABC notes into the frequency?
