The first 500 people who click the link in the description will get 2 free months of Skillshare <a href='https://skl.sh/12tone23' target='_blank' rel='nofollow'>Premium</a> The past century has seen the rise of lots of new styles of music, from jazz to rock to hip-hop to funk, but at the heart of it all sits possibly the most important musical invention in American history: The Blues. The genre lent a voice to struggling communities in the late 1800s, and it's persisted in one form or another ever since, helping shape the musical vocabulary of a nation and the world. You can't understand modern music without understanding the Blues, and you can learn a lot about the Blues just by studying its signature song form: The 12-Bar Blues. It's an iconic device that's been used to great effect by artists in all sorts of styles for over a century, and it just might be the most influential chord progression ever written. <a href='https://www.patreon.com/12tonevideos' target='_blank' rel='nofollow'>Patreon</a> <a href='http://standard.tv/12tone' target='_blank' rel='nofollow'>Merch</a> <a href='https://discord.gg/yTGvQ4P' target='_blank' rel='nofollow'>Discord</a> Mailing <a href='http://eepurl.com/bCTDaj' target='_blank' rel='nofollow'>List</a> <a href='https://www.facebook.com/12tonevideos' target='_blank' rel='nofollow'>Facebook</a> <a href='https://twitter.com/12tonevideos' target='_blank' rel='nofollow'>Twitter</a> <a href='https://www.instagram.com/12tonevideos/' target='_blank' rel='nofollow'>Instagram</a> Email: 12tonevideos@gmail.com <a href='https://youtu.be/b_dzYeMqwFg' target='_blank' rel='nofollow'>Last</a> Script w/ <a href='https://docs.google.com/document/d/1yqDbAG0vEmwhj7O4Q_A6biJS6ojey8_Q2kfupfN9UJQ/edit?usp=sharing' target='_blank' rel='nofollow'>sources</a> Huge thanks to our Elephant of the Month Club members: Susan Jones Jill Jones Duck Ron Jones Howard Levine Brian Etheredge Gabi Ghita Elaine Pratt Ken Arnold Len Lanphar Paul Ward Benjamin DeLillo William (Bill) Boston Owen Campbell-Moore Anton Smyk Chris Prentice Jack Carlson Dov Zazkis James Treacy Bagshaw Christopher Lucas Hendrik Payer Andrew Beals Thomas Morley Jacob Helwig Duncan Dempsey Patrick James Morley David Rapoport Braum Meakes Derek Parnell Noah Gray Hendrik Stüwe Darius Rudominer Dan Bonelli And thanks as well to Corvi, Henry Reich, Gene Lushtak, Eugene Bulkin, Logan Jones, Abram Thiessen, Anna Work, Oliver, Jc Bq, Adam Neely, nico, Michael Fieseler, Rick Lees, Ben LaRose, Dave Mayer, Davis Sprague, rhandhom1, Paul Quine, CodenaCrow, Nikolay Semyonov, Arnas, Sarah Spath, Skylar J Eckdahl, Harold Gonzales, Caroline Simpson, Marc Himmelberger, Chris Borland, Michael Alan Dorman, Daniel Gilchrist, Blake Boyd, Trevor, Michael McCormick, Dmitry Jemerov, Ian Seymour, Charles Gaskell, Luke Rihn, Elliot Burke, Alex Atanasyan, Alex Knauth, Elliot Jay O'Neill, Tom Evans, Greg Borenstein, Tim S., Elias Simon, Elliot Winkler, Jerry D.
