Using MPlayer as a music/guitar trainer

Say you are interested in figuring out how to play a blues lick in a video that somebody posted on YouTube. Here’s what you do:

Download the video to your computer using one of Firefox’ many video download extensions (e.g. Video DownloadHelper). Then fire up a terminal window and type

mplayer -af scaletempo -speed 0.5 '~/Desktop/myvideo.mp4'

This will open MPlayer playing the video at half speed (‘-speed 0.5’) while preserving the pitch. Of course, you can use values other than 0.5.
