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

| Solution description: | The pattern models the physi- cal 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 prop- erty 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.
