In modern academia, music theory is a subfield of musicology, the wider study of musical cultures and history. Music theory is often concerned with abstract musical aspects such as tuning and tonal systems, scales, consonance and dissonance, and rhythmic relationships. In addition, there is also a body of theory concerning practical aspects ...
Advanced Placement ( AP) [ 4] is a program in the United States and Canada created by the College Board. AP offers undergraduate university-level curricula and examinations to high school students. Colleges and universities in the US and elsewhere may grant placement and course credit to students who obtain qualifying scores on the examinations.
Musical acoustics or music acoustics is a multidisciplinary field that combines knowledge from physics, [ 1 ][ 2 ][ 3 ] psychophysics, [ 4 ] organology [ 5 ] (classification of the instruments), physiology, [ 6 ] music theory, [ 7 ] ethnomusicology, [ 8 ] signal processing and instrument building, [ 9 ] among other disciplines.
Philosophy of music is the study of "fundamental questions about the nature and value of music and our experience of it". [1] The philosophical study of music has many connections with philosophical questions in metaphysics and aesthetics. The expression was born in the 19th century and has been used especially as the name of a discipline since ...
In psychoacoustics, a pure tone is a sound with a sinusoidal waveform; that is, a sine wave of constant frequency, phase-shift, and amplitude. [ 1] By extension, in signal processing a single-frequency tone or pure tone is a purely sinusoidal signal (e.g., a voltage). A pure tone has the property – unique among real-valued wave shapes ...

Key signature change example: C major to C minor. In music, modulation is the change from one tonality ( tonic, or tonal center) to another. This may or may not be accompanied by a change in key signature (a key change ). Modulations articulate or create the structure or form of many pieces, as well as add interest.
A theory of everything ( TOE ), final theory, ultimate theory, unified field theory, or master theory is a hypothetical, singular, all-encompassing, coherent theoretical framework of physics that fully explains and links together all aspects of the universe. [ 1]: 6 Finding a theory of everything is one of the major unsolved problems in physics ...
