Decision:
Both ideas accentuate the letter "O" and a veiled note. I will describe only the final version of the chosen logo. I wrote the "O" in a pen-like stroke to add a bit of classicism, but I wanted something more lively and moving.
I remembered the experiment with starch. Сorn starch and water make a fluid that is liquid, but solid under the percussive action of the speaker, and exposure to sound makes it dance. Therefore, my O became three - a reference to the speaker, and had extra bends. Then, choosing the arrangement of the words, I saw how "ra" and "dd" coincide and that they resemble a double note, so I decided to take advantage of this and work a little on these letters.
