Pure tones

[Clarkmon22 He/Him]

On the Coppermind, it says that "The pulsing which comes from the Well of Ascension is a pure tone of Scadrial."

Does this mean that a seeker could locate any perpendicularity, as long as they were a really good seeker or hemalurgically spiked? why wasn't Vin drawn to the pits?

We have no indications that any other perpendicularity broadcasts it's tone and rhythm the same way that the Well of Ascension did (which Leras specifically set-up to work that way on a 1024 year cycle). The Well was designed to choose a Vessel 16 years before it was Full, and to begin broadcasting it's Tone and Rhythm to lead the chosen to the Well.

In the most recent Hero of Ages annotation, you said that Preservation chose Vin to be the recipient of the power, just as Preservation had chosen Alendi previously (thus, this was why Ruin had manipulated the Prophecies). Was Alendi also chosen precisely sixteen years before the Well of Ascension's power returned?

Brandon Sanderson (paraphrased)

Yes. He was chosen exactly sixteen years before, but he was a bit older then Vin when he was chosen.

Is that tone and rhythm stuff universal to the Shards and Investiture elsewhere?

Brandon Sanderson

The tones can be expanded to other Shards and Invested Arts around the cosmere.

Are the Allomantic pulses a Seeker hears (like drum beats) related to the tones of Preservation, then?

Brandon Sanderson

Yes, they are.

The terms kinetic and static Investiture were introduced in Rhythm of War, but not defined or explained.

Brandon Sanderson

Yes.

What are kinetic and static Investiture?

Brandon Sanderson

Good question. So I've been talking about this for a while, so some of the arcanists out there know. Kinetic is a thing I'm defining that the Investiture is being actively expressed and used, and so it has certain effects. For instance, you're gonna see sand get charged by kinetic Investiture but not necessarily by static Investiture. Static Investiture being Investiture that is stuck in a sphere. If you just walk by with that sphere, particularly if it's in a bag or something, the white sand's not going to see anything. But if you are actively using it to do something, if you have created or are maintaining something, if you are flying or you are using one of the Surges, then we call that kinetic. And kinetic Investiture is going to show up much more easily to someone who can replicate the abilities of a Seeker, who can hear pulses. These are the things the spren notice when someone is using their powers. This is white sand. There are just many things in the cosmere that respond to Investiture being used in some way, and when it is not being used it is harder to hear, locate, or reference.

Even Venli did not sense the Perpendicularity directly - despite being a singer to hear Roshar, Stone had to help her find the way and hear the Beat and listen from partially in Shadesmar. 

Ch 89-90:

They reached the central plateau itself. Above, the humans had set up watchposts hanging over the chasms. They were tattered and broken, presumably damaged in the battle. Perhaps they had been used in an effort to spot Deepest Ones. Nervously, Venli peeked into Shadesmar to see if any Fused were nearby, but found only an expanse of beads—with glowing flames higher up, representing the fighting humans and singers.

Except … the beating … was lower. Beneath the beads. Beneath the ground.

“What?” Thude whispered.

“It’s underneath us,” Venli whispered. She pressed her hand against the chasm wall as she crouched in the flowing water.

Yes, the stones said to her. You are nearly here.
<snip>

     Rocks sang as Venli and the others reached the end of the tunnel. They found a magnificent golden pool of light.

Awespren burst around them, six of them, floating blue balls that expanded as they faded into nothing.

This pool was hidden in a rocky cavern with no exits, directly beneath the main Narak plateau.
<snip>

It had been hidden, at least until now. Until …

Until, Timbre guessed, someone arrived who was bonded to both a spren of Odium and a spren of Honor. Venli. Had Odium somehow masked his pool using Honor? Or was it something else? 

 

It's likely that a Seeker would need a valid Connection to the Investiture in the Well to Seek it. 

It's possible that other Perpendicularities' tones and rhtyhm can be sensed, but we don't have enough data to know if that happens automatically, requires certain conditions, or has to be prevented when a Shard does not want it found (or some other circumstances). In Theory, a skilled enough Seeker, with the proper Intent should be able to sense a perpendicularity if it is Pulsing.

Sorry there is not a definitive answer. Hope that helps anyway.
