MusicalInstrument-Acoustic acoustic instrument acoustic instruments http://en.wikipedia.org/wiki/Acoustic_music Instances are instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwPu5fpwpEbGdrcN5Y29ycA" class="cyc_term">MusicalInstrument_Acoustic</a> and <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjf7JwpEbGdrcN5Y29ycA" class="cyc_term">Keyboard_MusicalInstrument</a>. All instances share the characteristic feature that depressing a key will entrain a mechanical process that results in the plucking of a taut string, causing a vibration which is audible as a musical tone. Thus, instances are also considered instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjXt5wpEbGdrcN5Y29ycA" class="cyc_term">StringInstrument</a>. The process is similar to that used in instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViiWZwpEbGdrcN5Y29ycA" class="cyc_term">Piano_Acoustic</a>, with the signal difference that in instances of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViiWZwpEbGdrcN5Y29ycA" class="cyc_term">Piano_Acoustic</a> the string is hammered, not plucked. harpsichord Harpsichord Banjo banjo stringed instrument of the guitar family Musical instruments which are struck to produce a sound.

Each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWXYgJwpEbGdrcN5Y29ycA" class="cyc_term">ExistingObjectType</a> is a specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVj27ZwpEbGdrcN5Y29ycA" class="cyc_term">PartiallyTangible</a> (q.v.). Moreover, each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWXYgJwpEbGdrcN5Y29ycA" class="cyc_term">ExistingObjectType</a> is a collection that is temporally stuff-like (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVitN5wpEbGdrcN5Y29ycA" class="cyc_term">TemporalStuffType</a>) but physically-spatially object-like (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVirnZwpEbGdrcN5Y29ycA" class="cyc_term">ObjectType</a>) -- i.e. object-like with respect to some physical-spatial part-whole predicate (e.g. some specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4r8a2smPXcQdiEoJhcx65EiQ" class="cyc_term">properPhysicalDecompositions</a>). Consider the collection <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwJaXepwpEbGdrcN5Y29ycA" class="cyc_term">BookCopy</a>. <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwJaXepwpEbGdrcN5Y29ycA" class="cyc_term">BookCopy</a> is a specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVj27ZwpEbGdrcN5Y29ycA" class="cyc_term">PartiallyTangible</a>. Further, <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwJaXepwpEbGdrcN5Y29ycA" class="cyc_term">BookCopy</a> is temporally stuff-like: any one of the <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvWn4OZwpEbGdrcN5Y29ycA" class="cyc_term">timeSlices</a> of a given copy <code>COPY</code> of (say) "Moby Dick" is still a copy of "Moby Dick". (Most collections of tangible objects are temporally stuff-like in this way.) But <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwJaXepwpEbGdrcN5Y29ycA" class="cyc_term">BookCopy</a> is spatially object-like: if we take a scalpel and slice <code>COPY</code> into ten pieces, each piece is not a copy of "Moby Dick".

MusicalInstrument-Acoustic acoustic instrument MusicalInstrument A collection of physical devices. An instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjI6JwpEbGdrcN5Y29ycA" class="cyc_term">MusicalInstrument</a> is a device that (in the standard case) is designed to be manipulated by a person to generate music -- that is, s/he successively plays the notes of the music by manipulating the instrument during the playing. Possibly the player also supplies by muscle power the force that produces the sound, but possibly it uses another power source (e.g., electricity, or steam). The music may or may not be of his or her own composition, but the player's actions determine that the notes are produced by the instrument (in the standard sense). Note: If the directive role of the human player is subsumed by the device -- as it is, e.g., by some electronic instruments which are programmable and/or pre-programmed to produce music or musical sounds -- the device loses some of its instrument-like quality, and some automated uses may be abnormal cases of `playing' an instrument. An older but analogous example is: player pianos. If the device is pre-programmed so that humans can't direct the music at all, then the device is not a musical instrument (but a musical device) -- for example, music boxes. Also excluded from <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjI6JwpEbGdrcN5Y29ycA" class="cyc_term">MusicalInstrument</a> are devices which produce music `at random' (such as wind chimes). Devices such as radios, tape decks, CD players, which are used to play wholly pre-recorded or otherwise other-controlled music, are also not included in this collection. musical instrument The collection of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjI6JwpEbGdrcN5Y29ycA" class="cyc_term">MusicalInstrument</a>s that is not powered by electronic or some other `artificial' means.

MusicalInstrument-Acoustic acoustic instrument Pretty String (<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwLSVCpwpEbGdrcN5Y29ycA" class="cyc_term">prettyString</a> TERM STRING) means that STRING is the English word or expression (sequence of words) commonly used to refer to TERM. The predicate <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwLSVCpwpEbGdrcN5Y29ycA" class="cyc_term">prettyString</a> is used by the code which generates CycL to English paraphrases, but its applicability is not restricted to this use. prettyString kind of artifact not distinguished by brand or model An instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rHQdVmB_TEdaAAABQ2rksLw" class="cyc_term">SecondOrderCollection</a> and a specialization of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwO3H5pwpEbGdrcN5Y29ycA" class="cyc_term">ArtifactType</a>. Each instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rejmDbrF_QdeIENT1qpbYzQ" class="cyc_term">ArtifactTypeByGenericCategory</a> is a collection of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVkH_ZwpEbGdrcN5Y29ycA" class="cyc_term">Artifact</a>s grouped together according to some feature(s) other than brand or model.

For example, the collection <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjaoJwpEbGdrcN5Y29ycA" class="cyc_term">Dog</a> is an instance of <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rpPHhAOB1EdqAAAACs6hRXg" class="cyc_term">SpatiallyDisjointObjectType</a>, since dogs do not spatially overlap. Even pregnant dogs do not spatially overlap the pups they bear; rather, pregnant dogs contain their unborn pups.
