Communicating Ideas 2

Lesson objectives identify the advantages and

disadvantages of using common applications to communicate ideas: Multimedia presentations Printing flyers and posters Websites Music production Cartoon animations

Music production 1 In the same way that it

is now very easy to create printed documents using IT, it has also become easier to create and edit music with the help of computers.

Music production 2To produce a musical score (sheets of

written notes), you no longer need to write every note down by hand.

You can use a WYSIWYG editor to write the music on the computer, edit it, print copies, etc.

Music production 3 It is possible to play music into a

computer and the notes will be recorded - not as sound, but as digital music data.Your analogue music is converted into digital data using an analogue-to-digital convertor (ADC).

Music production 4Once you have music data in a computer

you can use the computer to play back the music (converting the digital data back into sound with an ADC).

You can add effects to the music, simulate thousands of different instruments, add new 'tracks' of music over the top, etc.

Music production 5A computer can be used

to control musical instruments (or it can be controlled by instruments) using a system called Musical Instrument Digital Interface (MIDI).

Most musical keyboards have MIDI connections, as do many electric guitars.

Music production – tasks:

Original recordings can be modifiedElectronic instruments can be played

back through special effects generators

Synthesizers can combine simple wave forms to produce complex musical creations

Electronic organs & pianos can mimic any instrument

Music scores can be generated from the music!

Automatic correction of music in a score

No need to understand music notation to write music

Print scores

Cartoon animationsAnimations can

be produced using computer hardware and software.

With 3D animation, objects are designed on a computer and a 3D skeleton is produced.

The parts of the skeleton are moved by the animator using key frames , tweening and morphing
