We Let My Son Listen to Music While Studying for One Month. Here Are the Results.

The music-during-homework debate in our house has been running since approximately P2 and shows no sign of resolution. My son's position: music helps him concentrate. My position: this is a myth that children have propagated because they want music on and "it helps me concentrate" is more persuasive than "I prefer it." His position is not unreasonable. Mine was not based on any actual observation.

In October, I decided to stop arguing and start tracking.

The setup: four weeks, alternating. Week 1: no music, silence. Week 2: his music, his choice (instrumental lofi playlist he'd curated, which I will admit was considerably more pleasant than I expected). Week 3: silence. Week 4: music. I tracked three things: homework completion time (in minutes), my subjective assessment of his focus quality (on a very rough scale), and his marks on any worksheets or assignments returned that week.

I am aware this is not a rigorous study. I am one parent with one child and a four-week window. I am also a person who works in finance and finds it genuinely difficult to have a debate without data, even bad data, so we are working with what we have.

Completion time: Weeks 1 and 3 (silence): average 48 minutes per evening. Weeks 2 and 4 (music): average 41 minutes per evening. He finished seven minutes faster with music. I checked whether he was rushing — whether the faster completion correlated with worse quality. It did not, based on the worksheet marks.

My subjective focus assessment: This is where I have to be honest about the limits of what I was measuring. I found it harder to assess focus during the music weeks because I was less present in the room during those weeks. I noticed that when music was on I checked in less frequently — the music was a social signal that he wanted some distance, perhaps — and my absence may have allowed him to focus more, not the music itself. Variable I hadn't considered.

Worksheet results: No meaningful difference. Across the four weeks, his marks were within normal variation regardless of condition. The music did not appear to help or hurt the actual output quality.

My stress levels: This is the data point I hadn't planned to collect and which turned out to be the most interesting. Music weeks: I was, measurably, calmer during homework time. The music functioned as a buffer. It reduced my tendency to listen to the quality of his silence (is that a struggling silence? a daydreaming silence?) and intervene. My interventions were probably not helpful. The music reduced them.

So here is what I actually concluded: the music was, at worst, neutral on his performance and completion. It may have improved completion time slightly, though I can't isolate whether this was the music itself or my changed behaviour in response to it. It materially reduced my stress levels during homework time, which — and I am not proud of how long it took me to consider this — affects my son's stress levels, because children are extremely good at sensing parental stress even when it is not expressed.

We have settled on the following arrangement: instrumental music is allowed during homework, no lyrics (he accepted this constraint more easily than I expected), on a small bluetooth speaker not in his ears, at low volume. Not every evening — some evenings he prefers silence. He chooses, and this I think is also part of what made it work: when the rule was "no music" it was a site of conflict, and the conflict was the problem. When the rule is "you choose," he sometimes chooses silence.

What I learned from this experiment that I didn't expect to learn: I had been enforcing the no-music rule primarily because it was the rule I'd absorbed from some general principle about concentration, not because I had observed it working. And I had been enforcing it with a consistency that was creating nightly friction. The friction was costing more than the music ever could have.

This is probably a metaphor for other things. I'll think about that later.
