Dear Sir/Madam,
I hope these videos that have speed control function such as YouTube.
Sometimes I saw Tomo San plays some great licks that I also want to learn, but it’s difficult to me.
At this time, there is no speed-adjustment option on this Vimeo platform, but I believe that a free plug-in available for Chrome (and, possibly, other web browsers) will provide what you need. Tomo and I have not tested any speed control plug-in.
