Sound 1: traffic lights

traffic lights are a very interesting sound, they always have a consistent tempo and the texture and pitch can vary depending on where the particular traffic light is placed, for example, if it is placed somewhere with little to no cars or buildings around, the sound will be more flat and dull whereas a traffic light placed in an area with a lot of cars and buildings the sound will be a lot more reverb and dense

sound 2: keyboard

the keyboard that I type on every day is extremely pleasing to listen to. it has no rhythm because I am constantly typing at different speeds but because the keyboard is mechanical the pitch is very flat and there is not a lot of texture there I think that is why it is so pleasing to listen to even for a long duration of time
