Anatomy for singers the easy way: The Diaphragm.

We are going to talk about the very important

characteristics of the diaphragm so that you understand its role in breathing for singing.

Let's start right now.

So let's play a game "True or False?"

I am going to show you three statements and you tell me if you think that they are true

or not. Let's start.

1. The diaphragm inhales and exhales.

2.

The diaphragm supports the sound.

3.

You can feel your diaphragm when you inhale.

Now, pause the video and think about these statements.

Are they true or false?

By the way, if you don't know what the diaphragm is, no worries, I am going to talk about it

very soon.

Just take a guess for now.

Ok.

If you said that all three statements are false, you are absolutely right!

Congratulations!

These three statements are very common myths floating around in the singing community.

And some singers build their skills based on this kind of information and as a result

of not having good knowledge about their instrument, they don't progress.

So now, let's talk a little bit about the diaphragm and let's see if you will be able

to restate the three statements into facts.

The diaphragm is a dome-shaped muscle that spans across the bottom of the ribcage.

It is attached to the spine at the back, to the bottom edge of the ribcage on the sides

and to the sternum (breast bone) on the front.

The diaphragm separates the chest cavity from the abdominal cavity.

The diaphragm is the major muscle of inhalation because it is responsible for about 70% of

inhaled air.

During inhalation, the diaphragm contracts, flattens and moves downward.

This downward movement pushes on the inner organs in your abdomen.

You can observe this direct effect of the descending diaphragm as your belly gets pushed

out during inhalation.

It is not the diaphragm you see and feel moving in and out.

It is the inner organs getting pushed out due to descending of the diaphragm.

When the diaphragm moves down, the lungs expand.

As a result, the air pressure in the lungs decreases, which sucks air into the lungs.

During exhalation, the diaphragm relaxes and returns up to its dome-shaped relaxed position.

The inner abdominal organs also return to their "normal" position and you can observe

this as your belly moves in.

The lungs decrease in volume, which causes the air to rush out of the lungs.

There you have it!

The diaphragm.

But how does this knowledge help us create a flexible, yet powerful system to support

the sound?

Once you understand the basic structures and principles, you can start discovering and

exploring your own body, you can start learning how to use it to your advantage and how to

control it.

Now, let's reformulate the three statements into facts that we can build our skills upon.

1.

The diaphragm inhales.

It relaxes during exhalation.

2.

The diaphragm does not support the sound because it is very difficult to control a muscle in

the state of relaxation.

3.

You cannot feel your diaphragm when you inhale.

What you feel is the inner organs and the abdominal wall moving out as a result of the

descending diaphragm.

This was just a short anatomy and physiology lesson.

As you can see, it does not have to be boring or hard to learn.

Ok.

That is all for today.

Thank you very much for watching this video and I cannot wait to the next one.

Happy breathing and singing.

Take care.

A Burning Man for Healthcare Geeks, Callie Fisher, StartUp Health: NOW #134 - Duration: 3:09.

Tell us about the StartUp Health Festival and then also tell us about

what's new this year. The StartUp Health Festival is our premiere event. It is happening in

January. 2018 will be our third year of the StartUp Health Festival. And,

basically, it's a two-day takeover in San Francisco. We set up a pop-up space, it's

really exciting. We had over 1,500 people, which was really energetic. It was

incredible. From the speakers to just the attendees, all the networking, all the

meetings that were happening, it was just full of excitement and such a buzz. And

in January we had Vice President Biden speak, which was really exciting. And, from

a planning perspective, it was also, really, I would say a unique experience,

and definitely something that was, you know, really a learning experience and

really fun for us. The secret service. An added layer. Yes. What are some of the other types of people that

come? There's Health Transformers, there's all sorts of innovators. Maybe describe

some of the the people that come to the StartUp Health Festival. Definitely. Well, we

have all of our Health Transformers. So, it's really an opportunity for them to

really, you know, be the stars, to get to meet, not only each other in person,

because, you know, they're from all over the world, but connect with investors,

connect with, you know, healthcare leaders, c-suite executives, everyone that is

basically in town at that time. So, one of the things that I think's been a lot of

fun about the festival. We've created this thing called the StartUp Health Cafe. We are

all crammed together in a small little space and that created a lot of energy. Yeah.

This year we're trying something new. What are we doing this year? We have a

brand new location, which is really exciting. It's got three floors, so in

years past it's been a lot of fun. As you mentioned, the cafe, it was where everyone

would network, we had our main stage area, which is where everyone would come and

listen to all of our incredible speakers, like Bill McDermott and Vice President

Biden. And then we had a VIP area. So, that was all on one floor. This year we

have three different floors. So, all of those things get their own area. It's

going to fit four times as many people and we're going to have two stages this

year. So, or, next year. So, one stage will be devoted entirely to Health

Transformers. Which is really exciting. We'll get a chance to learn more about

their mission, their moonshots, their companies, and get them on

stage. So, is it more like Burning Man or more like Lollapalooza? Well, people have

said that it's the Burning Man of the J.P. Morgan Festival, or the J.P. Morgan

Healthcare Conference. I think if there was a Burning Man for healthcare geeks,

this would be it. Thank you for everything that you do to support the

community here at StartUp Health. Of course.

Cross product of vectors - Mathematics for Engineers - Vectors - TU Delft - Duration: 6:51.

Hi there!

If you think about a way of multiplying vectors, it turns out that you have several possible definitions:

until now you have seen you can multiply a vector and a scalar to obtain another vector.

In the previous lesson you learned about the dot product:

an operation on two vectors having a scalar as its outcome.

Another name for the dot product is the inner product by the way.

This product is closely related to orthogonal projections.

In this video you will find out about another operation on two vectors,

whose result is another vector, having some nice properties!

This operation is called the cross product or the outer product.

Let's think about the following question:

Given two vectors u and v in three dimensional space,

find another vector w that is perpendicular to both of them.

How can you find it?

Not a difficult question to answer you will probably say:

you know after all that this vector then should have the property

that the dot product with both vectors equals zero.

For our example this means you have to solve the following two equations:

minus w1 plus 2 times w2 plus 2 times w3 equals 0

and w1 minus w2 plus w3 equals 0.

Okay, this is not a problem, except that you now have two equations with three unknowns!

You may not know how to solve such a system yet,

but in a course on linear algebra you will learn how to do this.

Furthermore you will discover that there are infinitely many solutions.

Because if you multiply any nonzero vector that is perpendicular to the two given vectors,

by a nonzero constant you get another vector that is perpendicular to the two given vectors.

And this you can do forever, you just change the length of the perpendicular vector.

One thing you could do to try to overcome this non-uniqueness is to restrict your attention

to unit vectors.

But even then, you see that there are still two possible directions

in which the vector you are looking for can point.

To choose one of the two directions, there is nice rule called the right-hand rule.

If the fingers of your right hand curl from u to v,

then your thumb points in the direction of the vector perpendicular to u and v that we will choose.

This vector is the cross product of u and v.

So if this is u and this is v,

then the direction of the vector you are looking for is this way.

But if this is u and this is v, I have to put my hand like this

and you see that the vector points downwards!

To get the point of this rule you should really do the movement yourself!

Fortunately, there is a procedure to compute the cross product that is really straightforward.

I call it the Amsterdam method, because it uses crosses just as on the famous small pillars

that can be found in Amsterdam.

Let's do an example with our vectors u and v:

write down a table with two columns and six rows.

In the first three entries of the first column you put the vector u

and in the next three entries you do this again.

Then do the same thing for the second column but now with the vector v.

Then remove the first and last rows and put three crosses in the table as shown.

Now compute the three components of the new vector w, using the crosses in the table.

Each cross means upper left multiplied with lower right minus lower left multiplied with upper right.

If you practice this in the exercises you will find out that this Amsterdam method gives

a fast way to find the vector w.

A quick check will reassure you that the vector w is indeed perpendicular to both u and v.

The cross product was introduced by the famous British mathematician Rowan Hamilton

in the early nineteenth century.

In general the formula found from the Amsterdam method to compute the cross product

of the vectors u and v is shown here.

I now challenge you to prove for yourself that the vector w is indeed perpendicular to the vectors u and v!

Given two vectors u and v in three dimensional space,

you know how to find the direction of the cross product using the right hand rule.

The length of the cross product may seem somewhat mysterious still.

This length, though, has a clear and nice geometric interpretation.

If u and v are not scalar multiples of each other, they actually lie in a plane:

a plane is a two dimensional subset of the three dimensional space.

Then, you can define the parallellogram spanned by u and v.

This parallellogram then has an area; and guess what?!

This area is equal to the length of the cross product of u and v.

Knowing how to compute the cross product is one thing,

the question of course is why on earth would you want to be able to do such a thing?

Well, there are numerous applications in physics and in mathematics.

In physics for instance you encounter it in electromagnetism

and mechanics on rotating bodies (like the earth).

In mathematics the cross product is used to compute the volume of a parallelepiped,

and to determine the equations of planes in three dimensional space.

You will learn more about computing these volumes and planes in the next videos.

But first: do some exercises to compute cross products

and study the properties of the cross product listed in the text following this video!
