How to Load Handel in Matlab

Learn how to make Matlab play a clip from Handel's "Hallelujah Chorus"

Matlab is a matrix-based technical computing program and programming language for engineers. It contains several hidden features. "Load Handel" is a reference to one of these hidden features. This particular feature, also known as an "easter egg," allows users to hear a special audio when a few lines of code are typed in the command window. The audio clip is from the "Hallelujah Chorus" which is composed by George Frideric Handel.

Instructions

1. Open Matlab.

2. Type "load handel" in the command window.

3. Skip a line and type "sound(y,Fs)."

4. Press "Enter" and wait for the clip to play.

Tips & Warnings

• Contrary to customary Matlab code syntax, you don't need to type semicolons at the end of the lines of code in this tutorial.

• Make sure to type "handel" instead of "handle" or the audio clip will not play.
