The Sound of Practice

I'm hearing a piano sound from outside of my suite now.
There is a person who has a piano in his/her suite, and I often hear the person's practicing sound. The sound is not as beautiful as a CD, nor the melody is perfect, but I somehow feel very comfortable.

Actually, I don't feel good for the piano harmony when I hear it from CDs; from them, I feel more comfortable with the sound of synthesizer or other instruments. But from somewhere outside, the sound is not so clear; therefore, it's OK. Moreover, I feel good for knowing that someone is making his/her effort tirelessly. It gives me some energy to work my own study.
