If you are a guitarist excelling in choro and want to learn more about the various rhythm patterns in choro and how to accompany them on your instrument in a choro ensemble, then there is good news for you. An accomplished choro guitarist, Abdallah Harati, has prepared and uploaded several pedagogical examples on his website to teach you the right approach. - I'll insert a couple of examples below of the short videos (- also available at YouTube) to give you an impression of Abdallah Harati's lecture on the different patterns in accompanying choro on the violão/guitar. Each example has text in English to reach also non-Portuguese speaking learners, an excellent service to spread know-how and prepare you for Choro Day events later this week, I think.
