Music Representation Flashcards
Define Pitch?
The notion of pitch refers to a perceptual property that allows a listener to order a sound on a frequency related scale.
What is a Musical note?
: is a term which is used rather loose, while it can either relate to a musical symbol (when talking about score representations). As well as pitched sounds (when referring audio representations).
What is meant by pitch chroma?
is closely related to the twelve different pitch classes; for example C4 and C5 have the same chroma value of C. while all notes with the same chroma value belong to the same pitch class.
Name three types of way you might represent a piece of music?
Sheet, Symbolic and Audio representations.
What is meant by Symbolic representation?
Machine-readable data formats that represent musical entities.
What is meant by sheet music representation?
Visual representations of a score in printed form or in digitised images.
Sheet music describes a musical work using a formal language based on musical symbols and letters, depicted in a graphical-textual form.
What is meant by audio representation?
Representations of acoustic sound waves.
When one discretises pitches what does that lead too?
Discretising pitches leads to the notion of a musical scale
What is an Octave?
the interval between one note and another with half or double its fundamental frequency
What is meant by the Twelve- tone equal tempered scale?
one octave is subdivided into 12 equally spaced scale steps.
What is the Chromatic scale?
ordering all notes in the equal tempered scale according to their pitches.
Describe the process of Optical Music Recognition?
the process of converting digital images of sheet music into symbolic music representations.
What are some issues with Optical Music Recognition?
The system misses notes, incorrect key signatures and transposing errors with certain instruments instruments.
What does the term audio refer too??
refers to the transmission, reception or reproduction of sounds that lie within the limits of human hearing.
Describe what the waveform refers too??
The change in air pressure at a certain location can be represented by a pressure-time plot.
