Jingle Bells

Jingle Bells, la tan famosa canción de navidad de todos los tiempos, creada por James Pierport y renovada por diversos artistas actuales, ha sido un single que no envejece.

Los pasos para crearlo son:

1. Instalar paquetes de música

#install.packages("devtools")

#library(devtools)
devtools::install_github("keithmcnulty/Rmusic", build_vignettes = TRUE)

## WARNING: Rtools is required to build R packages, but is not currently installed.
## 
## Please download and install Rtools 4.2 from https://cran.r-project.org/bin/windows/Rtools/ or https://www.r-project.org/nosvn/winutf8/ucrt3/.

## Skipping install of 'Rmusic' from a github remote, the SHA1 (07d3c027) has not changed since last install.
##   Use `force = TRUE` to force installation

2. Crear las notas como string

jbells_pitch <- paste(
  "E E E",
  "E E E",
  "E G C D",
  "E",
  "F F F F",
  "F E E E",
  "E D D E",
  "D G",
  "E E E",
  "E E E",
  "E G C D",
  "E",
  "F F F F",
  "F E E E E",
  "G G F D",
  "C",
  "G3 E D C",
  "G3",
  "G3 G3 G3 E D C",
  "A3",
  "A3 F E D",
  "B3",
  "G G F D",
  "E",
  "G3 E D C",
  "G3",
  "G3 E D C",
  "A3 A3", 
  "A3 F E D",
  "G G G G A G F D",
  "C C5 B A G F G",
  "E E E G C D",
  "E E E G C D",
  "E F G A C E D F",
  "E C D E F G A G",
  "F F F F F F",
  "F E E E E E",
  "E D D D D E",
  "D D E F G F E D",
  "E E E G C D",
  "E E E G C D",
  "E F G A C E D F",
  "E C D E F G A G",
  "F F F F F F",
  "F E E E E E",
  "G C5 B A G F E D",
  "C C E G C5"
)

jbells_pitch <- strsplit(jbells_pitch, " ")[[1]]

3. Se crea el vector de duración

jbells_duration <- c(
  1, 1, 2, 
  1, 1, 2, 
  1, 1, 1.5, 0.5, 
  4, 
  1, 1, 1, 1, 
  1, 1, 1, 1, 
  1, 1, 1, 1,
  2, 2,
  1, 1, 2, 
  1, 1, 2, 
  1, 1, 1.5, 0.5, 
  4, 
  1, 1, 1, 1, 
  1, 1, 1, 0.5, 0.5, 
  1, 1, 1, 1,
  4,
  1, 1, 1, 1, 
  3, .5, .5, 
  1, 1, 1, 1, 
  4,
  1, 1, 1, 1, 
  4,
  1, 1, 1, 1, 
  4,
  1, 1, 1, 1, 
  4,
  1, 1, 1, 1, 
  3, 1,
  1, 1, 1, 1,
  1, 1, 1, 1, 
  1, 1, 1, 1, 
  1, 0.5, 0.5, 0.5, 0.5, 0.5, 0.5,
  1, 1, 0.5, 0.5, 0.5, 0.5, 
  1, 1, 0.5, 0.5, 0.5, 0.5,
  0.5, 0.5, 0.5, 0.5, 0.5, 0.5, 0.5, 0.5,
  0.5, 0.5, 0.5, 0.5, 0.5, 0.5, 0.5, 0.5,
  1, 0.5, 0.5, 1, 0.5, 0.5, 
  1, 0.5, 0.5, 1, 0.5, 0.5, 
  1, 0.5, 0.5, 0.5, 0.5, 1,
  1, 0.33, 0.33, 0.33, 1, 0.33, 0.33, 0.33,
  1, 1, 0.5, 0.5, 0.5, 0.5, 
  1, 1, 0.5, 0.5, 0.5, 0.5,
  0.5, 0.5, 0.5, 0.5, 0.5, 0.5, 0.5, 0.5,
  0.5, 0.5, 0.5, 0.5, 0.5, 0.5, 0.5, 0.5,
  1, 0.5, 0.5, 1, 0.5, 0.5, 
  1, 0.5, 0.5, 1, 0.5, 0.5, 
  0.5, 0.5, 0.5, 0.5, 0.5, 0.5, 0.5, 0.5,
  1, 0.33, 0.33, 0.33, 2
)

4.Se reproduce y se crea un archivo WAV

Rmusic::play_music(jbells_pitch, jbells_duration)

Rmusic::save_music(jbells_pitch, jbells_duration, output_file = "jbells.wav")

Comentarios:

No se puede correr en la versión 4.1.1 debido a que sale cierto error dentro del programa.

Conclusión y Aprendizajes:

Dentro de esta corta y divertida actividad, pudimos comprender acerca de los mil y un usos que se le puede dar a R Studio.

Como apasionada por la música se aprecia que puedan meter este tipo de funciones dentro de programas en la actualidad, según lo aprendido, al saber las notas y tempos de cada canción se podría lograr este tipo de desarrollo de programas fácilmente.
