Mars Gelfo, internationally touring professional hornist and founder of High Range Magic

Founder

Mars Gelfo

The method was built by internationally touring professional hornist, Mars Gelfo.

Mars went from struggle and discomfort above third-space C to playing double C’s daily without even needing to warm up. He spent 20 years gathering and testing solutions, distilling what worked into a step-by-step system.

The same practices, principles, and secrets that landed him gigs with the San Francisco Symphony, the Philadelphia Orchestra, and stages around the world are now structured into a clear, optimized action plan you can follow yourself.

In their own words

We have worked with players in every walk of life, from amateurs to principals. Here is what they say about it.

I played the end of Concertstuck and the entire scale up to E6, not just once, but multiple times!

My high range is no longer konzertSTUCK! There is no way I could have safely attempted the first horn part before High Range Magic. To have recorded proof of myself playing one of the most epic moments is surreal.

Sebastian Dunn

NZ Symphony Orchestra

High C was generally my ceiling. Thanks to High Range Magic, miraculously I can climb those stairs and push that ceiling higher and higher.

Christopher Gough

Principal Horn, BBC Scottish Symphony

Going into High Range Magic I was a scared and timid player. Now I have relaxed, confident control over 5 octaves. High Range Magic completely changed the way I approach the horn.

Justin Phillips

High Range Magic Graduate

I increased my range by at least 1 octave, playing easily up to high G above high C. I have so much more confidence and ability. It feels so good to hear my improvements.

Debbie Lowes

High Range Magic Graduate

My first concert since joining High Range Magic and I haven't felt so comfortable in many years. The high notes were not stressful and I got to the last page with plenty of fuel in the tank. At 67 years of age!

Mervyn Stephens

High Range Magic Graduate

The founder of my brass quintet said, 'Man, Jack, you sound great. Where are you auditioning?' I hadn't yet told him I was.

Jack Levoska

High Range Magic Graduate

This method has changed my mind-set and my life. My increase in range, endurance and confidence has put me in a position where I am in demand more than ever.

Alan Pefley

High Range Magic Graduate

I am so glad I took the plunge. This is the horn player I was always meant to be!

Marian

High Range Magic Graduate

The day I nailed the double high C squeak and didn't even know it. I learned that I am an amazing high horn player. The sky is the limit, just go for it!

Ellen Klein

High Range Magic Graduate

I can play a high F above high C without even setting or thinking about it. The high range has no limits, and I can partake in the high range party anytime I choose.

Mat Boatright

High Range Magic Graduate

I played high notes I didn't think were even possible on the horn. I can play a double high C. I found a renewed sense of joy and drive in my music-making.
