What Can a Song Do That Takes More Than Thirty Seconds?
Streaming gives the first half minute a significance that comes from accounting.
Spotify counts a song stream after thirty seconds of playback. That is a definition of the event that appears in its statistics. It is tempting to turn it into a universal explanation for every short introduction on the service. Musicians have been trying to catch an ear since long before anybody needed a dashboard. The more interesting problem is what happens when a boundary introduced for counting becomes a boundary people feel obliged to compose around. Spotify for Artists on counting streams.
An immediate hook can do fabulous work. One sound can make a person stick their head through a doorway. When the sound also gives you the reason the song will last for three minutes, speed has a point. The pressure begins when those first seconds are asked to supply something the song could only make in time. A false sense of calm is the subject of some arrangements. A slow beginning lets a listener acquire an expectation sturdy enough to make its failure matter. The money at the end of an interval has very little to say about what those seconds need to contain.
The start is part of the story
Take a piece that begins with a singer against a high chord. The bass enters later and establishes a key the first chord only appeared to belong to. The listener has an experience of having heard accurately and understood prematurely. A short extract of the bass entrance can show that the notes work. It cannot convey the misapprehension the entrance corrects. Something of the piece exists in the amount of time the listener spent believing the earlier version.
Most people have good reasons to leave a recording sooner. They might recognise a sound they dislike or need the room quiet. There is real information in that decision. There is also a difference between a useful instrument for counting decisions and a theory about what decisions a piece of music deserves. If a composer treats the latter as settled before the piece has begun, the industry has had a hand in ordering the work without ever commissioning it.
I would defend attention that is earned over an uncomfortable stretch of time. A composer has to take some responsibility for making that stretch worth living through. The listener should have to wait because there is something a song can give them at its own pace. Spending thirty seconds under an expectation is sometimes the thing the record came to offer.
