Question: Do both directors of films The Spiral Road and Hollywood Shuffle share the same nationality?

<P0-S0> In music theory, the spiral array model is an extended type of pitch space. <P0-S1> A mathematical model involving concentric helices( an" array of spirals"), it represents human perceptions of pitches, chords and keys in the same geometric space. <P0-S2> It was proposed in 2000 by Elaine Chew in her MIT doctoral thesis" Toward a Mathematical Model of Tonality". <P0-S3> Further research by Chew and others have produced modifications of the spiral array model, and, applied it to various problems in music theory and practice, such as key finding( symbolic and audio), pitch spelling, tonal segmentation, similarity assessment, and musical humor. <P0-S4> The extensions and applications are described in" Mathematical and Computational Modeling of Tonality: Theory and Applications". <P0-S5> The spiral array model can be viewed as a generalized tonnetz, which maps pitches into a two- dimensional lattice( array) structure. <P0-S6> The spiral array wraps up the two- dimensional tonnetz into a three- dimensional lattice, and models higher order structures such as chords and keys in the interior of the lattice space. <P0-S7> This allows the spiral array model to produce geometric interpretations of relationships between low- and high- level structures. <P0-S8> For example, it is possible to model and measure geometrically the distance between a particular pitch and a particular key, both represented as points in the spiral array space. <P0-S9> To preserve pitch spelling, because musically A# ≠ Bb in their function and usage, the spiral array does not assume enharmonic equivalence, i.e. it does not fold into a torus. <P0-S10> The spatial relationships between pitches, between chords, and between keys agree with those in other representations of tonal space. <P0-S11> The model and its real- time algorithms have been implemented in the tonal visualisation software MuSA. <P0-S12> RT( Music on the Spiral Array. Real- Time) and a free app, MuSA _RT, both of which have been used in music education videos and in live performance. <SEP> <P1-S0> Townsend is best known for directing the films" Hollywood Shuffle"( 1987)," Eddie Murphy Raw"( 1987)," The Meteor Man"( 1993)," The Five Heartbeats"( 1991) and various other films and stand- up specials. <P1-S1> He is especially known for his eponymous self- titled character, Robert Peterson as the starring role as on The WB sitcom" The Parent' Hood"( 1995 – 1999), a series which he created and of which directed select episodes. <P1-S2> Townsend is also known for his role as Donald" Duck" Matthews in his 1991 film" The Five Heartbeats." <P1-S3> He later wrote, directed and produced Making The Five Heartbeats( 2018), a documentary film about the production process and behind the scenes insight into creating the film. <P1-S4> Townsend is also known for his production company Townsend Entertainment which has produced films" Playin' for LoveIn the Hive" and more. <P1-S5> During the 1980s and early – 1990s, Townsend gained national exposure through his stand- up comedy routines and appearances on" The Tonight Show Starring Johnny Carson". <P1-S6> Townsend has worked with talent including Halle Berry, Morgan Freeman, Chris Tucker, Beyoncé, Denzel Washington and many more. <P1-S7> Robert Townsend( born February 6, 1957) is an American actor, director, comedian, and writer. <SEP> <P2-S0> Hollywood Shuffle is a 1987 American satirical comedy film about the racial stereotypes of African Americans in film and television. <P2-S1> The film tracks the attempts of Bobby Taylor to become a successful actor and the mental and external roadblocks he encounters, represented through a series of interspersed vignettes and fantasies. <P2-S2> Produced, directed, and co-written by Robert Townsend, the film is semi-autobiographical, reflecting Townsend's experiences as a black actor when he was told he was not" black enough" for certain roles. <SEP> <P3-S0> The film was released by Universal- International in the United States in 1962, the same year that Mulligan's other movie" To Kill a Mockingbird" became a critical and commercial success. <P3-S1> The Spiral Road is a 1962 American adventure drama film directed by Robert Mulligan and starring Rock Hudson, Burl Ives, Gena Rowlands, and Geoffrey Keen. <P3-S2> The movie was filmed in Suriname in South America and was shot in Eastmancolor. <SEP> <P4-S0> Robert Patrick Mulligan( August 23, 1925 – December 20, 2008) was an American film and television director best known as the director of humanistic American dramas, including" To Kill a Mockingbird"( 1962)," Summer of' 42"( 1971)," The Other"( 1972)," Same Time, Next Year"( 1978) and" The Man in the Moon"( 1991). <P4-S1> He was also known in the 1960s for his extensive collaborations with producer Alan J. Pakula. <P4-S2> He was the elder brother of actor Richard Mulligan. <SEP> <P5-S0> Mr. Right is a 2009 British film directed by David Morris and Jacqui Morris. <P5-S1> The jointly- made gay- themed film is the debut for both directors.
