| Intent: | This content ODP models the acoustic features of a music note played in a performance. |

| Solution description: | The pattern models the physical characteristics that can be extracted from the sound wave produced by an instrument playing a musical note. The MusicalObject class is connected to four classes that describe these physical characteristics, namely duration, sound intensity, frequency and envelope. The MusicObjectDuration class expresses the duration in seconds of the musical object, by means of the object property hasDurationInSeconds. In the same way, the musical intensity is modelled via the SoundIntensity class. Frequency is modelled by means of the class Frequency and its sub-classes FundamentalFrequency and PartialFrequency. For each expressed frequency, the magnitude of the frequency is also indicated using the hasFrequencyMagnitude object property. Finally, the Envelope class is connected to four object properties that describe the envelope of the waveform according to the ADSR model, namely hasAttack, hasSustain, hasDecay and hasRelease. |

Elements
The Musicalobject Content OP locally defines the following ontology elements:
Envelope (owl:Class) The envelope of a musical object's soundwave. In physics and engineering, the envelope of an oscillating signal is a smooth curve outlining its extremes.
Envelope page FundamentalFrequency (owl:Class) The foundamental frequency of a musical object. The fundamental frequency is defined as the frequency of the lowest constituing partial of a signal.
FundamentalFrequency page PartialFrequency (owl:Class) A frequency other than the foundamental Frequencyuency.
PartialFrequency page MusicalObject (owl:Class) A musical object is the result of the realisation of a set of instructions that the musician or a computer system uses to realise a piece of music (e.g. music notation).
MusicalObject page SoundIntensity (owl:Class) The intensity of the sound produced by a musical object.
SoundIntensity page
hasEnvelope (owl:ObjectProperty) Connects a musical object to the envelope of the soundwave it produces.
hasEnvelope page hasFrequency (owl:ObjectProperty) Connects a musical object to the frequencies it produces.
hasFrequency page hasSoundIntensity (owl:ObjectProperty) Connects a musical object to the sound intensity produced.
hasSoundIntensity page isDurationOf (owl:ObjectProperty) Inverse of hasDuration. Connects the duration of a musical event to the musical event itself.
isDurationOf page isEnvelopeOf (owl:ObjectProperty) Inverse of hasEvelope. Connects the envelope of a musical event to the musical event itself.
isEnvelopeOf page isFrequencyOf (owl:ObjectProperty) Inverse of hasFrequency. Connects the frequency of a musical event to the musical event itself.
isFrequencyOf page isSoundIntensityOf (owl:ObjectProperty) Inverse of hasSoundIntensity. Connects the sound intensity of a musical event to the musical event itself.
isSoundIntensityOf page
hasAttack (owl:DatatypeProperty) Describes the attack time (expressed in seconds) of the soundwave's envelope, according to the ADSR model.
hasAttack page hasDecay (owl:DatatypeProperty) Describes the decay time (epressed in seconds) of the soundwave's envelope, according to the ADSR model.
hasDecay page hasDurationInSeconds (owl:DatatypeProperty) Expresses the duration in seconds of a musical object.
hasDurationInSeconds page hasFrequencyMagnitude (owl:DatatypeProperty) The amplitude of a frequency component of a complex sound.
hasFrequencyMagnitude page hasIntensityValue (owl:DatatypeProperty) The value of the sound intensity of a musical object.
hasIntensityValue page hasRelease (owl:DatatypeProperty) Describes the release time (epressed in seconds) of the soundwave's envelope, according to the ADSR model.
hasRelease page hasSustain (owl:DatatypeProperty) Describes the sustain time (epressed in seconds) of the soundwave's envelope, according to the ADSR model.
