NAME
Music::Harmonica::TabsCreator - Convert tunes into harmonica tabs
SYNOPSIS
use Music::Harmonica::TabsCreator qw(sheet_to_tab_rendered);
say sheet_to_tab_rendered('C D E F G A B C');DESCRIPTION
tune_to_tab
my %tabs = tune_to_tab($tune)Convert a sheet music into harmonica tablatures. Sheets can be specified using a flexible syntax like: C D E F, C# Db, Do ré mi, C4 C5, A B > C D E F G A B > C D D C < B A (that last example shows how you can switch the current octave if you don’t specify octave numbers with each note).
For more details on the tune format, see the GitHub README.
The function returns a hash (not a hash-ref) where the keys are the identifier of a given harmonica (you can learn more about that harmonica using the get_harmonica_details() function), and the values are hash-refs where the keys are the key of the harmonica to use to play the tune. The values associated to these keys are arrays of tablatures. Each tablature is itself an array of strings, one for each note making up the tablature.
tune_to_tab_rendered
say tune_to_tab_rendered('Kb B C D E F G A B C');This is the same thing as tune_to_tab but the output is returned in a string ready to be displayed to a user. Also this function will not die (instead a user friendly error will be returned directly in the string).
get_harmonica_details
my %details = get_harmonica_details($harmonica_id);Given an ID that is one of the key of the hash returned by tune_to_tab() function this returns a hash containing two keys: name and tags where the first has a human readable name for the harmonica and the second a list of tags relevant to the harmonica.
