Below is where you can make a "virtual tip" for me during these crazy times when I am still out of all of my performing work (which has been my main income for over 25 years) as I keep busy working on new products and merchandise here on BadAss Harmonica, as well as new lessons, videos, and webinars where I share proceeds with other musicians...

If you are able and willing to send a Tip, it is appreciated MUCH more than you know. Nothing is expected, and I just really appreciate the people who have been checking in with me and my friends, and who continue to purchase lessons, amps, microphones, t-shirts, and other merchandise from me. It's a lifesaver right now, for sure.

Student Testimonial
“It has been my pleasure to have become one of Dennis' students…from the time we had our first 'in person' session, to our current setup of doing the online sessions. I have become a full time tounge-blocker thanks to him! Also, my ears have been hearing & listening for things I never would have picked up on my own. I must say, I am a much better & more comfortable player, since I started sessions with Dennis!”

“Dennis Gruenling's online lessons are as good as any face to face lessons. The setting is just as intimate - it becomes just you and Dennis. I think his lessons are better than anything else one might find...Dennis is one of the premier contemporary players of the day, and yet teaches you as if he cares more about your progress than anything else."

“I have taken two 'semesters' of lessons with Dennis. As an intermediate player when I began, Dennis has definitely helped me achieve the next level in my playing. Dennis’ approach to music theory has helped my understanding of music tremendously. I now consider myself a musician, not just a harp player. Even long distance, these lessons are a great value for the money!”

"Dennis is the perfect teacher – he points you in the correct direction when you need help, he makes you feel comfortable, and he helps if you are feeling frustrated. I have now gotten to the level that I am in my own blues band and I never could have made it to this point without Dennis.”
