People get used to everything, including communication forms. When we read reports on the spread of COVID-19 throughout the year, we can no longer perceive the data adequately. Is 10,000 cases a big number of a huge number? 1123 deaths per day - how terrible is that? We just look at these numbers and feel nothing. But if we transfer this data into another form, the emotional impact of the message on the recipients increases significantly. So we did. We transformed data on the spread of COVID-19 in Nizhny Novgorod region into music. Task: To tell about Artificial Intelligence Center "Gorky" as part of the Nizhny Novgorod Region stand at SPIEF Details: "Artificial Intelligence Center "Gorky" developed a high-precision COVID-19 propagation model. It allowed taking accurate administrative decisions to prevent the spread of the disease. Solution: We have created a symphony dedicated to the doctors' heroism and the memory of those who died according to the dataset of COVID-19 spread in Nizhny Novgorod region. All sounds are based on real events: Sick people were represented by the first piano melody. People who have recovered were represented by the second piano melody. The deceased were represented by clicking sounds. How we did it: 1. We took a dataset on COVID-19 in Nizhny Novgorod region. 2. We wrote a code for converting numerical data into notes for Ableton. 3. We launched the sonification process and transferred all the data into 88 keys of the synthesizer. 4. Then we set values for harmony. 5. One day became one cycle. 6. The higher was the value on the graphs, the higher was the note. 7. A little mastering, and the Symphony of a new feat was ready! Target audience: Guests of the Nizhny Novgorod Region stand at SPIEF Results: 1. After the first hour, our work was urgently posted on the Nizhny Novgorod 800th anniversary website. It caused a stir. 2. We received gratitude from Veronika Skvortsova, the former Minister of Health. 3. The symphony became the headliner of the stand. https://soundcloud.com/h01xpphykyzx/matematicheskiy-trek
