Pitch Definition and 118 Threads

Pitch is a perceptual property of sounds that allows their ordering on a frequency-related scale,
or more commonly, pitch is the quality that makes it possible to judge sounds as "higher" and "lower" in the sense associated with musical melodies.
Pitch can be determined only in sounds that have a frequency that is clear and stable enough to distinguish from noise.
Pitch is a major auditory attribute of musical tones, along with duration, loudness, and timbre.Pitch may be quantified as a frequency, but pitch is not a purely objective physical property; it is a subjective psychoacoustical attribute of sound. Historically, the study of pitch and pitch perception has been a central problem in psychoacoustics, and has been instrumental in forming and testing theories of sound representation, processing, and perception in the auditory system.

    Role of pitch in swing and seam movement of cricket ball

    Recently I attended a lecture related to the physics behind swing of cricket ball. But the speaker dealt with the swing before pitching(and dealt loosely with late swing). He took only the effects of air in consideration. I am interested to know how the pitch effects the swing(or seam movement)...

    What causes the feedback (a noise increasing in intensity and pitch)?

    What causes the feedback (a noise increasing in intensity and pitch) sometimes heard when people speak through microphones? I'm sure I have enough background to understand an explanation, I've just never thought about it before.

    Solving for the Vertical Distance of a 101 mph Pitch

    Homework Statement One of the fastest recorded pitches in major-league baseball, thrown by Billy Wagner in 2003, was clocked at 101.0 mi/h (Fig. P3.22). If a pitch were thrown horizontally with this velocity, how far would the ball fall vertically (in feet) by the time it reached home plate...

    Pitch Speed Revalive to Bat Speed

    Homework Statement It's for a physics project, in which I'm trying to calculate the velocity applied to a fastball thrown at 95mph, when the bat speed of a hitter is 86.99mph. The weight of the ball is 5oz, the weight of the bat 31oz, and we'll go with contact on the ball at .005s.(This is...

    Why Does Coffee Pitch Rise When Stirred?

    I don't know which mentor to address this question to so I'm trying it here. After I have stirred my coffee I always tap the spoon on the lip of the cup. As I do so the pitch keeps rising until the coffee is no longer moving. I've been curious about this for years and hope somebody can answer...

    Why are pitch and frequency similiar to loudness and intensity?

    Why are pitch and frequency similar to loudness and intensity? I also have one more question! I have a test coming up on the properties of sound things likethe spped of sound etc? Does anyone have like an old test or something i can use to help study?

    Musical question regarding concert pitch/philosophical pitch

    Hi there Can someone please help me with this question I have no idea how to work it out... A tuning called 'philosophical pitch' has C4 (Middle C) at 256Hz. What is the difference in cents between notes at this pitch standard and those in modern concert pitch (A4 at 440Hz)? Thanks in...

    Noisy TV's: Is There a Reason for the High Pitch Sound?

    Im curious about this question because of the TV's at school. I can hear a TV on in a house with extrenious noise even if the TV is muted. I asked my science teacher if she could hear the TV when it was on and she said she heard the sound but that's all. I hear a very high pitch noise when a TV...

    Understanding Clarinet Dynamics and Pitch

    As a clarinet student, i have always been told two things: 1.) to change your loudness, change the amount of air you send through the horn, not the speed at which you send air through it. if you change the speed, you will change the pitch. 1.) you can change your pitch by tightening or...

    Arm length and pitch speed in softball

    The big event of the softball season, the Women's College World Series, begins Thursday. One aspect I find interesting is that many of the dominant pitchers are very tall. Many of you are probably familiar with the underhand delivery of fastpitch softball, which implicates angular motion. The...

    Screw Gauge Pitch: Length of Main Scale Division?

    In a screw gauge, the pitch is defined as the distance traveled in one rotation. Is it also equal to the length of one main scale division? If the length of one main scale division is not given, then can we take it to be equal to the pitch? Or do we take it as equal to some other default value.
