For adults, a short review of the physics underlying music theory.
Using PSOLA to change the pitch of a speech signal without changing the voice quality.
This is a lesson in which the students will combine their knowledge of rhythm, pitch, and tone color with their imaginations to create original compositions about animals. They will use "Carnival of the Animals", by Saint-Saens, and "Peter and the Wolf",and other.
Learn about music for free. Informal music lessons and discussions of music theory. this site covers a wide range of topics about music.
Students are introduced to sound energy concepts and how engineers use sound energy. Through hands-on activities and demonstrations, students examine how we know sound exists by listening to and seeing sound waves. They learn to describe sound in terms of its pitch, volume and frequency. They explore how sound waves move through liquids, solids and gases. They also identify the different pitches and frequencies, and create high- and low-pitch sound waves.
In this video from Curious George, young children learn about pitch by playing a variety of drums. One hearing-impaired child experiences the different sounds through her hands instead of her ears.
An algorithm for modifying the pitch of a solo human voice in the frequency domain.
For middle school to adult, an explanation of the relationships between frequency, wavelength, and pitch.
This is a discussion as to the ideas and methods of finding the harmonics in a speech signal.
Hearing is a familiar and important human sense that is a topic naturally of interest to those who are curious about human biology. This unit will enable you to relate what you read to your own sensory experiences – and indeed many of the questions asked have exactly that function. This unit will be best understood by those with some biological understanding.
This is a lesson that introduces and reinforces the music concept of pitch.
Students learn about the frequency range of human hearing by collecting data from a website simulation. They analyze the data to determine the typical range for students in their classroom. Students participate in a collaborative effort to gather scientific data on humans for use in designing an engineering product.
The distance between two pitches is the interval between them. The name of an interval depends both on how the notes are written and the actual distance between the notes as measured in half steps.
This module discusses one technique used to change the length of a signal without changing its pitch.
Students design musical instruments inspired by what they learn in an experiment with beakers of different liquids. In the "research and investigate" stage of design, they experiment to determine the general relationship between pitch (frequency) and liquid density. They use their results to draw designs for instruments that can create sound at several different pitches.
"This course is a survey of perceptual and cognitive aspects of the psychology of music, with special emphasis on underlying neuronal and neurocomputational representations and mechanisms. Basic perceptual dimensions of hearing (pitch, timbre, consonance/roughness, loudness, auditory grouping) form salient qualities, contrasts, patterns and streams that are used in music to convey melody, harmony, rhythm and separate voices. Perceptual, cognitive, and neurophysiological aspects of the temporal dimension of music (rhythm, timing, duration, temporal expectation) are explored. Special topics include comparative, evolutionary, and developmental psychology of music perception, biological vs. cultural influences, Gestaltist vs. associationist vs. schema-based theories, comparison of music and speech perception, parallels between music cognition and language, music and cortical action, and the neural basis of music performance."
For high school and above, a discussion of the relationship of musical intervals and frequency ratios, with examples and exercises.
Students will learn to hear the differences between low, middle, and high pitches. They will be able to visualize these differences by looking at the low, middle, and high points of a mountain.
Part 1 of a three part series of videos explaining the connection between science and music. Part 1 Pitch and Frequency, Part 2 Pitch and Frequency continued, Part 3 Frequency and Harmonics
Description of the system to identify music pitches in text. This is the system employed by the Acoustical Society of America and many music journals.
