I am older trying to learn to play the accordion. I learn by watching slowly and through video. I learned that Windows Media Player allows you to slow down videos by Right-Clicking -> go to Enhancements -> Video -> Play Speed Settings.
In looking for new tunes to learn I would see some on YouTube but didn’t know how to download them. I thought I should search this. Which when I did I realized I have done this before and have been to the same site I was about to go to. Basically when you are on the YouTube video you want type “ss” after the www. and before “Youtube.com”. Give is second the click the text on the right that mentions .MP4.
This video is where I found the download info.
