Greater pressure creates higher volume (the auditory meaning of volume, not the geometric). Pitch is a function of the periodic frequency of pressure variation. 2-dimensional representation of pressure over time is not in itself erroneous.

Perhaps over-simplified would be a better term. Yes, although trumpet tone is the application of that vibration to the air column shaped by the tube, not so much the brass tube itself. Raceway backpressure just makes it easier for us to produce vibration with our lips. Our embouchure must resist air movement if vibration is to result, but the pressure waves from that vibration perpetuate in air thanks to the inertia of that mass of air, not any raceway resistance to flow. But, he is on the right track.įor anyone who may doubt the above, kindly ponder why the flame produces a sound exiting the glass tube when the flame itself consumes air and burns without a said in Is Air Needed To Play The Trumpet: Unfortunately, he cannot explain the science for what he demonstrates. The prof in the vid below is a talented musician, not a scientist. This is why a trumpet having a D-shaped lead pipe will be easier to play for high notes than one having a semi-circular C lead pipe. If the right pressures are achieved, what we call 'partials' can result. Thus, a trumpet requires bends in the pipes the bends assist to create pressure. One factor is the resistance of the trumpet to help us create greater pressure. To achieve this, many factors must be combined. What we hear as high pitch from a trumpet is a function of both frequency and pressure: ie greater vibration and greater pressure, from the player. But here is a simple fact: sound is 3-dimensional and 2-factored. Sound is always depicted via 2-dimensional graph as a line to form a 'wave' this pictorially presents sound to have a frequency we can measure, but excludes entirely the factor of pressure. Unfortunately, the science we learn in high school is erroneous, and thus people carry this throughout their lives. For most of us, we need to exhale air against closed lips to produce a vibration/frequency. To produce a frequency, we need to apply a vibration to the tube: for us, the source is our lips. But, the tube must resist the air we apply: else no pressure will result. For most of us, this means we must blow air into the tube. To produce a pressure from the trumpet, we need to apply a pressure into the trumpet/tube.

No movement (ie displacement) of air is needed. What we perceive as sound is a function of 2 factors pressure and frequency. True, WE need air, but not for the reasons people think.
