Special way of encouraging!

One of the better decisions I made in recent years is picking up piano lessons. With Katja it was different from day one. Being a professional musician she has a very sharp eye to prevent you from making mistakes that are later hard to correct. During the lesson she has permanent awareness of the students state and is adjusting, always carefully adapted to your personal possibilities and limitations. A private lesson is really so as her focus is always with you and all distractions are cut out. Add to this her special way of encouraging people and transmitting her joy for music and the instrument is sure to make you want to come back.

A great Piano Teacher!

I have played piano for about 7 months and I have had the same teacher all the way. In my opinion I think Katja is a great teacher because if I need to reschedule a lesson, she is always flexible with the time. She is also great at helping me find out what the notes are and has amazing techniques for improving my skills. What makes Katja such an amazing teacher is she is not always too strict.

A gifted Teacher!

Katja is a gifted teacher who cares about the music as much as she cares for her students. She has an excellent balance between rigor and kindness, allowing her students to make regular progress in a warm atmosphere. She is also an exceptional classical and jazz performing artist, which is a wonderful source of inspiration for her students. I have very high standards in music education, my only regret is that we have not found Katja earlier. It is a true privilege to have a musician of this caliber teaching my child.

She acts like my friend!

When I have my lessons, she is always smiling and acts like my friend. Katja is great at getting me focused when I get distracted, when I say that she is like a friend I mean that when I am tired, she adapts to how I feel. For example: sometimes I tell her I am quite busy {when she asks me how I am} she gives me less work which makes it easier for me to do a good job without any stress. Sometimes I even do more work than asked!
