Video is the technology of electronically capturing, recording, processing, storing, transmitting, and reconstructing a sequence of still images representing scenes in motion.
Video technology was first developed for cathode ray tube (CRT) television systems, but several new technologies for video display devices have since been invented. Charles Ginsburg led an Ampex research team developing the first practical video tape recorder (VTR). In 1951 the first video tape recorder captured live images from television cameras by converting the camera's electrical impulses and saving the information onto magnetic video tape.
Video recorders sold for $50,000 in 1956, and videotape cost $300 per one-hour reel. However, prices steadily dropped over the years; in 1971, Sony began selling videocassette recorder (VCR) tapes to the public. After the invention of the DVD in 1997 and Blu-ray Disc in 2006, sales of videotape and tape equipment plummeted.
Later advances in computer technology allowed computers to capture, store, edit and transmit video clips.
Music is an art form whose medium is sound and silence. Its common elements are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics, and the sonic qualities of timbre and texture. The word derives from Greek μουσική (mousike; "art of the Muses").
The creation, performance, significance, and even the definition of music vary according to culture and social context. Music ranges from strictly organized compositions (and their recreation in performance), through improvisational music to aleatoric forms. Music can be divided into genres and subgenres, although the dividing lines and relationships between music genres are often subtle, sometimes open to individual interpretation, and occasionally controversial. Within "the arts", music may be classified as a performing art, a fine art, and auditory art. There is also a strong connection between music and mathematics.
To many people in many cultures, music is an important part of their way of life. Ancient Greek and Indian philosophers defined music as tones ordered horizontally as melodies and vertically as harmonies. Common sayings such as "the harmony of the spheres" and "it is music to my ears" point to the notion that music is often ordered and pleasant to listen to. However, 20th-century composer John Cage thought that any sound can be music, saying, for example, "There is no noise, only sound." Musicologist Jean-Jacques Nattiez summarizes the relativist, post-modern viewpoint: "The border between music and noise is always culturally defined—which implies that, even within a single society, this border does not always pass through the same place; in short, there is rarely a consensus ... By all accounts there is no single and intercultural universal concept defining what music might be."
Will tomorrow be better
When yesterday things got worse?
Just when I'm moving forward
You go and put me in reverse
And just because we were
That don't mean that we are meant to be
No, but who cares what tomorrow brings
If it can't make sense of you and me?
But I've got you
And I can't imagine any day without you
It makes me wanna shout
And I'm singin'
Oh-oh, oh-oh
Hold on, don't let go
Don't open your eyes just yet
Oh-oh, oh-oh
Hold on, don't let go
It's not time to wake up yet
It's too late
To cut you out
You're in my blood
You're gonna spread
Your smell, your taste
Your laugh
Stuck in my heart
And trapped in my head
But now I've got you
And I can't imagine any day without you
It makes me wanna shout
And I'm singin'
Oh-oh, oh-oh
Hold on, don't let go
It's not time to wake up yet
Oh-oh, oh-oh
Hold on, don't let go
Don't open your eyes just yet
If I could wake up
How I dreamt
I wouldn't feel
So tired
Your eyes
That laugh and cry
Can't seem the
Eyes of liars
But that don't mean
I love you less
And that don't mean
I want you more than right now
Baby, right now
Oh-oh, oh-oh
Hold on, don't let go
It's not time to wake up--
Oh-oh, oh-oh
Hold on, don't let go
Don't open your eyes just yet
Oh-oh, oh-oh
Hold on, don't let go
It's not time to wake up yet
Oh-oh, oh-oh
Hold on, don't let go
Don't open your eyes just yet
