How technology has influenced the distribution of music


Activity 1

To explain how technology has influenced the distribution of music

  • While listening to Eine Kleine Nachtmusik imagine the following: You are living in Europe in the 18th century. The wonder child Mozart’s (13) music is creating a stir. He composes and performs his own work. Would it be possible for you to listen to his music? If so, how would you do it?
  • Compare it to the current situation. Name the technological inventions that make it possible to listen to any music today.

How has music been distributed since the beginning of the 20th century?

The influence of technology on the development of instruments

  • Since the very first musical instrument there has been an important connection between music and technology. Listen to the following extracts to experience the difference in sound:
  • Harpsichord music from the 17th century (Baroque Period) by JS BACH
  • Piano music by F CHOPIN

The piano developed from the harpsichord. Of the most important technological developments with regard to the piano is that the instrument could produce crescendo and diminuendo (gradually louder and softer) and sustain notes by using the damper pedal (the pedal to the right).

  • Poème Électronique by EDGAR VARÈSE

Since 1950 electronic instruments, especially amplified instruments like the electrical guitar and piano have become more prominent. With the development of electronic and computer technology the composer can be both composer and performer. Recordings are made in studios that have recorders, synthesizers, computers and other equipment to mix and filter sounds. This enables the composer to make use of a very wide spectrum of sound.

  • Try to recognise the following:




Machine noises


Animal sounds

Electronic sounds

Activity 2 (group)

To debate the following quotation:

  • One of the most experimental classical composers of the 20th century is without a doubt John Cage. His famous (or is it notorious?) composition is 4’33” (1952).

Let’s perform this composition!

  • One learner is responsible for the tape recorder.
  • One learner must time the performance – the recording must be exactly 4’33”.
  • One learner seats himself in front of a piano (or other musical instrument) without playing! He is the performer.
  • The rest of the learners form the audience!
  • The educator is the conductor who shows exactly when to begin and when to stop.

Good: 1.....2......3......begin!

1 second, 2 seconds_________4 minutes 30 seconds, 4 minutes 31 seconds,4 minutes 32 seconds, 4 minutes 33 seconds STOP!

Now listen to the recording!

No music? Only sounds!

What is the aim of this composition?

According to the composer he tries to arrange the composition means in such a way that he doesn’t have any idea of what is going to happen! His purpose is to eliminate purpose. He wants people to learn to listen; not only to music, but to everyday sounds as well.

The unintentional sounds that the audience might produce are the music! Cage explains: “I try to arrange my composing means so that I will not have any knowledge of what might happen. My purpose is to eliminate purpose. The purpose would be achieved if people learned to listen.” This type of music is beneficial for better communication between composer and listener.

Jeffrey Reply
sure. what is your question?
okay, so you have 6 raised to the power of 2. what is that part of your answer
I don't understand what the A with approx sign and the boxed x mean
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
I'm not sure why it wrote it the other way
I got X =-6
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
oops. ignore that.
so you not have an equal sign anywhere in the original equation?
is it a question of log
Commplementary angles

or infinite solutions?
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

Yes, Nanotechnology has a very fast field of applications and their is always something new to do with it...

good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
can nanotechnology change the direction of the face of the world

At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
