Hi! Very useful video thanks, and i like other lessons of this guy too. Well, he says that to have fast train effect need to practice months, let’s see )) And now without oil think it goes better, my mouth adapting to the instrument - and lips are more relaxed now. My harp is in C, now i have the most simple for beginners, but later i will buy Marine Band Deluxe or Crossover (thinking between this two). As i know Sunny Boy Williamson played on Marine Band Deluxe… so i think this is good choice. This simple cheap harp that i have now is also harp )) jeje, at least i can practice tecniques, like one-note, and this train effect. And then when i’ll take a better harp in my lips i will not damage it, and will be ready to play for enjoy. ))
