Examples

# noteworthy class examples
x <- as_noteworthy("a, b, c ce_g")
x[[3]]
#> [1] "c"
x[[2]] <- paste0(transpose(x[2], 1), "~")
x
#> <Noteworthy string>
#>   Format: space-delimited time
#>   Values: a, c~ c <ce_g>

# noteinfo class examples
x <- as_noteinfo(c("4-", "t8(", "t8)", "t8x"))
x[[3]]
#> [1] "t8)"
x[[3]] <- c("t8]")
x
#> <Note info string>
#>   Format: vectorized time
#>   Values: 4- t8( t8] t8x

# music class examples
x <- as_music("c,~4 c,1 c'e_'g'4-.*2")
x[[3]]
#> [1] "c'e_'g'4-."
x[[3]] <- "c'e'g'8"
x
