One example of sounds that I hear everyday that I consider to contain musical elements would be the sound of car horns and sirens as they move across the roads as the Doppler effect takes place: changing pitch from high to low as it rolls away amongst the traffic. These horn like sounds hold rhythm in the interplay of the traffic or the designed sequence of the siren. Their texture cuts through the noise and rumble of street sounds with a piercing unnatural tone because they are electronic waveforms.

Another sound that seems to be somewhat concrete is the typing of the keyboards of laptop users, the texture seems to be even stronger when there is a mass of people simultaneously typing. It almost sounds like a bunch of crickets fluttering their wings harmoniously. There is definitely an individual rhythm to each person who types as they think and react to thoughts at their own pace. of course, the different materials and dimensions of the keyboards themselves create different pitch when keys are struck by users and so when many different sets of boards are being used at the same time in the same place there is a mesh of these different rhythms and pitches that creates a rather interesting sound, especially when users are thinking thoughts of a similar nature as reaction times to events are akin, yet the speed of people’s typing varies greatly.

The third everyday sound I would consider concrete or musical is the rustling of wind brushing amongst tree leaves. Depending on the speed of the wind on the day and amount of leaves still on the trees you will be able to hear different pitches or textures of essentially something similar to white noise. Another physical factor that comes into play is how young the leaves on the trees are… in the spring to summer they will be quite fresh and hold more moisture in them, thus as they brush amongst each other the sound created from this event will be similair to fabrics brushing. In opposition to this, in the autumn the leaves are dry and fragile. They create a satisfying crunch when stepped on or obtrusive slippery surface when wet. As the wind brushes against these dying leaves, there is a much more crispy sound in the air and tension as they may brush against one another alive for the last time.
