Every phone has a timer. Meditation ended up with its own kind because a kitchen timer solves the wrong half of the problem.
A kitchen timer tells you when the pasta is done. A meditation timer has to do that and be forgettable for the twenty minutes beforehand, and then end the sitting without startling you.
The one job
If the length is decided and something else is holding it, the question how long has it been? has nowhere to go.
That question is the most reliable intruder in an unguided sitting. Not a dramatic distraction. A small persistent one that arrives every couple of minutes and gets a plausible hearing each time. Handing the clock to something else does not make you concentrate better. It removes one specific thing to concentrate about.
Where the bells came from
Bells around a period of sitting are old, and they show up independently in several places.
In Zen practice a bell conventionally opens a period of zazen and another closes it, with the sound treated as part of the practice and not as a signal wrapped around it. Tibetan ritual sound comes from bells (ghanta), cymbals and gongs, used to mark transitions in liturgy. Standing bowls are worth a note here, since half the meditation apps in the world ship a sound called a Tibetan singing bowl: their association with Tibetan practice is largely a twentieth-century Western one, not an old monastic timing instrument. Many secular courses inherited the bell convention wholesale, usually without the framework around it.
What survived the borrowing is the shape. A sound to begin, a sound to end, quiet in between.
What a chime does that a clock cannot
Only the first of these is about time.
It ends the sitting from outside, so you do not have to be the one deciding when to stop.
It arrives instead of interrupting. A struck bowl or bell blooms and thins out over several seconds. Against a phone alarm the difference is between being called and being startled.
And it carries no language. A chime says that much time has passed and nothing else, which is why it can appear in the middle of a sitting without dragging you out of it.
Interval chimes
An interval chime is any sound partway through. The common arrangements:
- End only. One undivided stretch. Most common, and where most people stay.
- Halfway. A single sound in the middle. A quiet checkpoint: you find out where you are once,
- Every few minutes. A regular pulse. Used in some noting and body-scan styles to mark segments,
- An opening sound. A chime at the start too, so the sitting has an edge at both ends instead of
None of these is more advanced than the others. They are different amounts of structure.
The argument for fewer
A chime is an event, and an event is something the mind can start waiting for. With a sound every three minutes, some people find they spend the whole sitting in anticipation of the next one, which is clock-watching with extra steps.
That is the case for end-only, and why most people drift toward it. The regular pulse that steadies one person is the one that distracts another.
Listening to the chime rather than through it
One more use, easy to miss because it looks like the same feature.
In several traditions the closing sound is the last object of the sitting. You follow the tone all the way out, until you cannot tell whether it is still there or you are remembering it. Some instructions regard that vanishing point as the most interesting few seconds in the period.
Whether or not that appeals, it explains the preference for bowls and bells over tones that simply stop. You can follow a decay. There is nothing to follow in a beep.
What separates one from the timer you already have
All of it is about edges.
How it ends. A decaying sound lets a sitting finish over a couple of seconds. An alarm tone yanks.
Whether it can speak partway through. A kitchen timer has one event and it is the last one.
What it does when the screen locks. The unglamorous one, and where most improvised setups fall down. A sitting is a stretch of time during which you are deliberately not touching the phone, so the timer has to survive the screen going dark and the device deciding it is idle.
Whether it stays quiet. No notifications, no badge, nothing to dismiss afterwards.
A phone is an awkward place for this
Worth naming, since it is the device nearly everyone uses.
A phone is the object most engineered to interrupt you, and a sitting is a stretch of deliberate non-interruption. Every notification the phone would have shown is still queued behind the timer, and some will arrive over it unless something is done. Focus modes and Do Not Disturb are the usual handling. Face down across the room solves the visual half and none of the audible half.
A watch sidesteps a good deal of that. The sound can be a tap nobody else can hear, there is barely a screen to be tempted by, and the phone can be left in another room. The trade is that a watch is on your body, and some people are aware of it for the whole twenty minutes.
Choosing a chime sound
Two practical notes.
You will hear it a lot, and a sound that seems pleasant once can wear badly at four hundred repetitions. Plain beats impressive.
And volume is part of it. A chime at the end of twenty quiet minutes lands considerably louder than the same chime auditioned in a normal room. Most people set it quieter than they first think.
What Nanea does
Pick a length, from a few minutes to an hour, or open-ended with no fixed end. Pick a background sound or none. Set a chime at the end, at the halfway point, or at an interval. Press begin.
Then it stops having opinions. One hold-to-end control on screen and nothing else, sound that keeps playing with the phone locked, and the sitting recorded quietly afterwards.
