Your CDs arrived safe and sound. I've listened to the first two and worked on the exercises. I'm a 55 year young, professional principal french horn player and have been working in a top German symphony orchestra for the past 30 years. I listened to the bonus telephone interview today. I am blown away. The results, applying your voice exercises to my playing (and to my students) are phenomenal. Resonance plays a huge role in performing on a brass instrument and very few poeple understand much about it. I've picked up useful and practical information, from singers and voice coaches, that I've been able to adapt to brass playing. Explaining resonance is now easy using your nose, mouth, throat etc, approach. The killer though, is using double resonance. I have free at present and don't have to perform in the orchestra (and the hall) until the beginning of Febuary. However, I am itching to hear how my changed sound is in our hall. It has to be amazing. Your material has added wonderfully valuable understandings to my comprehension of what constitutes excellent quality brass player and has beautifully simplified my means of effectively communicating it to my students. There has been a lot of belly laughter, stunned ears and broad smiles in my teaching studio this week. I'm teaching a course to amateur wind and brass players next year and am looking forward to applying your teachings to this particular situation for the benefit of the people attending. Thanks a million. This is one of the few times in my life where I've been gladly reeling and with a huge smile on my face.

I thoroughly enjoyed Jonathan's Linguistic Wizardry in November 2006 in Glasgow, Jonathan's humour and at times subtle directness is charming and enables great learning. I experienced these 3 days and his evening sessions both as a participant and sometimes from a trainer's perspective. The courses gave me more insight into myself (which NLP always does!), as well as more info, and exciting and useful NLP to bring to my own trainees, trainers and clients, as well as my own life. Jonathan's voice and careful testing of the waters in respect of humour are also delightful. And I met some great people. He's really worth the money, go for it, enjoy it and learn.

The training was fantastic. The focus of the seminar is, of course, on improving the quality of one's voice. Jonathan kicked off the process by spending some time explaining to the group the basic concepts of how the human vocal mechanism works and what are the components that make up a pleasing voice. We then engaged in an extremely effective session in which Jonathan gave personal attention to each of the attendees to identify their unique strengths and weaknesses. I was frankly amazed at the ease, rapidity, and precision with which Jonathan was able to zero in on each person's challenges and potentials. In my own case, he was able to identify three specific areas on which I needed to focus in order to gain the most improvement. To be blunt, he was absolutely right on all three. We then spent time practicing various drills aimed at acquiring and/or strengthening various vocal skills. The drills themselves were generally quite fun and productive. During the drills on all three days, Jonathan would circulate among the various breakout groups and provide individualized feedback. His style of providing the feedback was invariably frank, yet always respectful and sensitive to the participants' feelings. At the end of the three days, my own three problem areas were, I believe, far less problematic thanks to Jonathan's expert guidance. The bottom line: If improving your vocal quality is something that interests you, I would unreservedly recommend Jonathan's seminar.

From my perspective, context and meaning are, if not everything, a very big slice of the cake. Jonathan Altfeld's 'Knowledge Engineering' has provided me with the tools and understanding to create contextual maps of any problem, with cause, effect AND meaning. This approach is very powerful, and allowed me to create breakthrough strategies immediately, with clarity and certainty of purpose. Beyond this, Jonathan is exceptionally wise and articulate about NLP and how to use it to effect meaningful, lasting change. He is also very approachable and generous, and a pleasure to work with.
