Practice Journal – When Chamber Music Reveals What Practice Can't

Today, I had my first rehearsal with a cellist for Rachmaninoff's Cello Sonata in G minor, Op. 19, third movement. I had spent the past couple of weeks practicing the piano part on my own, becoming increasingly comfortable with the notes and rhythms.

During the rehearsal, something interesting happened.

In one passage, the harmony suddenly sounded completely wrong. It wasn't just a note that felt slightly awkward. It immediately stood out because the piano and cello no longer fitted together. For a moment, I looked back at the score, checked the chord, and realised that I had been playing a wrong note all along.

What surprised me was that I had never noticed it while practicing alone.

When practicing by myself, it is easy to become focused on finger movements, rhythms, and fluency. If a wrong note still fits reasonably well under the hand, the ear can gradually accept it as "normal." After hearing it repeatedly, the mistake almost becomes invisible.

Playing with another musician changed everything.

The cello provided another voice in the harmony. Suddenly, the incorrect note created a clash that neither instrument could hide. The harmony immediately told me something was wrong.

I have always enjoyed making music with other musicians, but today's rehearsal reminded me why. Chamber music teaches us that listening is not a passive skill, it is an active part of performing. Sometimes, the best practice doesn't happen alone at the piano. It happens when another musician helps you hear something you couldn't hear by yourself.

The cellist and me engage in our first rehearsal session within a music studio.

Ensemble playing becomes another way of practicing. Sometimes our ears notice mistakes that our eyes and fingers have overlooked.
