This lecture was given to us after we were assigned our second brief.
We began with this quote:
'If you want to find the secrets of the universe, think in terms of energy, frequency, and vibration' -Nicola Telsa.
This is another way of explaining the importance of sound, which will be key for our project.
We began looking at the first way of visualising sound which was telegraphy in 1840. This created notation marks on paper which could be sent. However, morse code, invented by Samuel Morse was the first graphic representation of sound. Combined with telegraphy, this creates texts. This was a turning point in visualising sound.

Although it isn't very visually appealing, it is still used today and is an example of how sound can be visual.
The next example of visualising sound was mathematic notation which was called Bach. I did not fully understand this example but understood that it used maths to visually represent notes in music. The method was famously invented and used by Joseph Schillinger who used mathematical equations to translate music, art and design. A famous piece of his was the Skyline Melody.

This technique took real life images and turned them into musical phrases. This meant that it worked on two levels and literally was visualising sound. This technique is aesthetically pleasing to see and hear.
John Cage also composed music and his music sheets were incredibly visual. For example, Sub Rosa:

This follows a very literal example of how to visualise sound. However, it is outdated and has moved on from this.
Brian Eno was the next example we were given. He created an album 'music for airports' in 1978. Although this isn't literally visual, it is background music (also known as musak) and is not supposed to be listened to as you would regular music. This may make a place seem more pleasant and relaxed but people aren't supposed to be drawn to listen to the music and it isn't really supposed to be heard. In a way, this makes it visual as it has to fit with its environment and create a mood that will compliment a situation. This is an interesting type of music and is a concept to take into account when doing this project, particularly focusing on how music sets a tone.
Oscilloscopes were the next example we were given. These machines work with using frequency and oscillation and are still used today, although deemed old fashioned.
Karl Ferdinand was the inventor of this in 1897.

These machines use sound and vibration and translate them into waves which symbolise voltages. Again, this machine had no use to be graphically visual but is another way to visualise sound and this concept could be taken further. For example, the use of sound waves can be very visual and interesting.
Leon Theramin invented an instrument out of oscillating devices. The instrument is called a Theramin, which was one of the first electronic musical instruments. Although this music doesn't create image, you do have to move your hands around in a pattern to work it, which makes it quite a visual instrument with a very distinctive sound.

This could inspire other ideas such as how to physically visualise sound as it is an interesting concept and, it is true that not only modern concepts are the greatest.
Mary Ellen Brute was friends with Schillinger and Theramin. She created animation using oscilloscopes in 1953 which were far more visual that Schillinger's and Theramin's inventions. For example:

Harmonics and vibration was the next part of the lecture and for this we looked at Robert Hooke (1860) as he made the discovery that the motion of the glass plate he was experimenting with moved perpendicular to the flour on the plate he was experimenting with. The flour turned oval. This discovery showed that vibration could be visualised and was groundbreaking. It was rediscovered by Ernst Chladni in 1871 and started to discover the theory of sound.
We then looked at Hans Jenny who coined the term Cymaticas. It was known to occur on a surface, such as a plate, where you can visually see the vibrations on the surface. It has been used in the video, Science vs Music:

This is an excellent example of how sound can be visual and how amazing it could look. There is a lot of information of how to make sound physically visual within this video and although it is edited, it still looks very effective.
This lecture was a great introduction on the brief and I really enjoyed the information. However, a lot of the examples were physical and it would be nice to have some digital demonstrations. In another way, it is good to have more ideas that move away from solely working on a computer and these examples definitely have inspired me to do so.
