Keywords

💡Auditory Illusion

An auditory illusion is a perception where the brain interprets sounds in a way that differs from the actual acoustic reality. In the context of the video, the auditory illusion refers to the Shepard Tone, a musical illusion where a sequence of sounds seems to ascend infinitely. The illusion tricks the listener into thinking the sound will continue to rise, but it's actually a loop that repeats. This concept is central to the video's theme, as the creator aims to explain and demonstrate how to produce this illusion using musical instruments and audio software.

💡Shepard Tone

The Shepard Tone is a specific type of auditory illusion named after the cognitive scientist Roger Shepard, who conceptualized it. It involves a sequence of sounds that appears to climb infinitely in pitch, but in reality, it is a loop of the same sequence. This concept is integral to the video, as the creator demonstrates how to produce this effect using a digital audio workstation and musical instruments.

💡Musical Scale

A musical scale is a series of musical notes arranged in ascending or descending order of pitch. In the video, the concept of a musical scale is used to explain the structure of the Shepard Tone, which mimics the pattern of a chromatic scale but with the illusion of endless ascent. The chromatic scale, in particular, consists of 12 pitches repeated in sequence, with seven white and five black notes on a piano keyboard.

💡Digital Audio Workstation

A digital audio workstation (DAW) is a software application used for recording, editing, and producing audio files. In the video, the DAW is the tool used to create the auditory illusion by allowing the creator to manipulate the pitch, timing, and volume of the audio tracks to produce the Shepard Tone effect.

💡Quantization

Quantization in music production refers to the process of aligning recorded notes to a grid, ensuring that they are perfectly in time with the tempo of the music. In the video, quantization is used to make the notes played on the MIDI keyboard loop seamlessly to create the illusion of an infinitely ascending scale.

💡Volume Automation

Volume automation in audio production is the process of automatically adjusting the volume levels of individual audio tracks over time. In the context of the video, volume automation is used to create the illusion of the Shepard Tone by gradually increasing the volume of the lower-pitched notes and decreasing the volume of the higher-pitched notes, giving the perception of an endless scale.

💡MIDI Keyboard

A MIDI keyboard is an electronic keyboard that generates MIDI signals, a type of digital data that represents musical information such as notes, pitch, and velocity. MIDI keyboards are widely used in music production to input and control virtual instruments in a digital audio workstation. In the video, the MIDI keyboard is used to play and record the notes that form the basis of the Shepard Tone illusion.

💡Looping

Looping in music production is the process of repeating a sequence of audio or musical notes continuously. In the video, looping is a key technique used to create the Shepard Tone illusion, as it involves repeating a sequence of notes to give the impression of an endless rise in pitch.

💡Pitch

Pitch in music refers to the perceived frequency of a sound, which determines how high or low a note sounds. In the context of the video, adjusting the pitch is essential for creating the Shepard Tone illusion, as it involves making the same sequence of notes sound higher or lower in pitch to mimic an ascending scale.

💡Musical Instruments

Musical instruments are devices used to produce musical sounds. In the video, the creator uses both a MIDI keyboard and a guitar to demonstrate the auditory illusion of the Shepard Tone. The instruments serve as the medium through which the illusion is created and experienced.

💡Home Recording

Home recording refers to the practice of recording music in a private or personal space, often using digital audio workstations and various instruments. In the video, the creator mentions a course on home recording, suggesting that learning this skill can enhance one's ability to produce music, including creating auditory illusions like the Shepard Tone.
