This is a difficult topic to write about because it involves people who are often excellent musicians and highly skilled teachers. What follows is not an attack, nor an attempt to discredit anyone’s artistry. It is an attempt to name a real issue that exists in music education and to do so with care.

Some teachers are exceptional at what they do. They possess deep technical knowledge, refined musical instincts, and a genuine ability to communicate ideas clearly during lessons. Students often improve quickly under their guidance. From the outside, everything appears ideal.

And yet, beneath that excellence, something unhealthy can take root.

When Excellence Becomes Territorial

These teachers are often very strong in the studio, but socially awkward outside it, and their collegial skills do not always match their pedagogical ones.

Over time, this mindset can shape how they train their students.

Instead of encouraging curiosity, they cultivate certainty. Instead of openness, they promote loyalty. Students are taught not only what to think, but who is right and who is wrong. Other approaches are dismissed outright rather than examined. Other teachers are portrayed as misguided, outdated, or incompetent.

The result is not confidence, but rigidity.

Dogma Instead of Inquiry

The most damaging outcome of this environment is that students become unteachable outside that single studio. They learn to argue rather than inquire. New ideas are met with resistance instead of curiosity. Guidance from other teachers is filtered through suspicion.

Technique becomes dogma.

This is especially tragic because music does not work that way. There are many paths to sound, many ways to solve physical and musical problems, and very few ideas that are truly new. Nearly everything we wrestle with today has already been considered deeply by generations of musicians before us.

Growth requires listening.

A Personal Experience

In my late teens, I was offered summer lessons by a cellist I admired. The experience was, in many ways, wonderful. I learned things I wished someone had shown me earlier. My playing improved.

What I did not recognize at the time was the subtle cost.

This teacher began to undermine my relationship with my primary instructor, encouraging me to question nearly everything she taught. He framed his own approach as correct and others as fundamentally flawed. I believed him. I was young and inexperienced, having studied with only a small number of teachers.

What I did not yet see was that his strained relationships extended beyond me. There were unresolved conflicts with colleagues, personal grievances that I was too naive to recognize. I became an unintentional participant in those tensions.

The damage was real. My relationship with my applied teacher deteriorated to the point that I lost my studio placement while majoring in cello. Although my university graciously arranged another teacher, the relationship that was broken never truly healed. Even decades later, that loss still matters.

The irony is painful: much of what the summer teacher showed me was genuinely valuable. But the posture in which it was delivered made it destructive.

Seeing It Again, From the Other Side

Years later, I encountered a college student who reminded me uncomfortably of my younger self. He had studied with a teacher who convinced him that he already possessed everything he needed. Other teachers were unnecessary. Different perspectives were irrelevant.

In lessons, curiosity had been replaced by defensiveness. The teacher was no longer a mentor, only a monitor. Every suggestion felt like a challenge to his identity.

He was ambitious, talented, and driven. And yet, growth stalled.

I recognized the pattern immediately, because I had lived it.

A Healthier Way Forward

Good teaching does not require exclusivity. Strong pedagogy does not fear conversation. Confidence does not need to diminish others.

We must approach ideas with openness and humility. We must trust that many thoughtful musicians have wrestled seriously with the same questions we face. Allowing others to speak into our work is not a weakness. It is how depth is formed.

If you find yourself studying with a teacher who isolates you, discourages outside input, or frames disagreement as disloyalty, learn to recognize the signs. Appreciate what you can learn, but do not absorb the poison.

At some point, growth may require moving on.

That decision does not negate what you learned. It simply affirms that music and learning are larger than any single voice.
