NoteBlokPlus makes it more convenient/comfortable to use note blocks on your server. It uses different mechanics for adjusting the pitch (tone) both up and down and adds a user-friendly visual design. Despite the fact that all the functionality of the plugin is designed for one block, it is very customizable and convenient. Even if you are from countries where the musical culture uses a different notation, you can easily customize this.
The mechanics of interacting with the note block are different from the standard minecraft mechanics. Normal interaction with the note block (standing straight) plays a sound. To change the pitch, you must use the sneak mode. The rest of the mechanics of the note block are preserved. The note block must still have an air block on top to make sound, and the bottom block determines the type of instrument. Player statistics continue to update according to the standard mechanics ("Note Blocks Played" / "Note Blocks Tuned")
Interaction with the note block is visualized on the screen, and displays not only the name of the note, but also the piano keyboard itself with the key pressed.

1. Play notes (straight mode).
Attacking or interacting with a note block while standing straight, plays the note. At the same time, the attack continues to affect the destruction of the block. In creative mode, the attack breaks the block without playing a note. Keep your sword in hand to work around this situation.

2. Adjust the note pitch/tone (sneak mode).
Attack while sneaking - decreases the pitch (tone). It also continues to affect the block, destroying it. In creative mode, the block breaking is canceled.
Interact while sneaking - increases the pitch (tone). Also interacts with the object in the hand, if it is not empty.

Playing the note and adjusting the pitch is accompanied by a message to the player that contains the name of the note and the piano keyboard with the key pressed. The message can be displayed in the center of the screen (title, subtitle), at the bottom of the screen (action bar) and in the player's chat. You can display arbitrary text in the message, as well as the name of the current note and/or a pseudo graphic representation of the piano keyboard with the key pressed.
Message display settings are set in the configuration file.

 # ABOUT INHERITANCE
 # Some sections can support inheritance (default values) from another configuration yaml file.
 # These sections use the string property "inheritance", which is optional.
 # The value is the path of the configuration yml-file relative to the folder of this file.
 # You can still override all or some of the properties after inheritance.
 # Be aware that properties with null values (~) do not override anything and default values will be used.
 # Inherited files can also be inherited from other files, etc. In such files, the property 'inheritance'
 # defines the path to the next one, but relative to the folder where the file itself is located.

   # The note that will correspond to the lowest note of the note block (ATM the lowest note in minecraft is F#0).
   # In this way, you can simulate the displacement of the notes range when displayed.
   # Defaults to 'F#0'
   first-note-as: ~
 
   # You can define note representations with three ways:
   #
   # 1. Basic formatting.
   # This method has the lowest priority and should be used first if possible. The note will be displayed as text
   # with three consecutive parts: tone, sharpness (if required) and octave number. Each part can be surrounded
   # by a prefix and a suffix. The entire note can also be surrounded by a prefix and suffix. The note construction
   # scheme will be as follows:
   #   note-prefix
   #     tone-prefix + TONE + tone-suffix
   #     sharped-prefix + sharped-symbol + sharped-suffix
   #     octave-prefix + OCTAVE NUMBER + octave-suffix
   #   note-suffix
   # The order of the tone, sharpness and octave number is determined by the parameters "swap-tone-sharp" and
   # "put-octave-first". To swap the output of tone and sharpness set "swap-tone-sharp" parameter to true.
   # To place the octave number at the beginning set "put-octave-first" parameter to true.
   # TONE will take on values as tone names. By default they are C,D,E,F,G,A,B (from Do to Si).
   # You can override some or all of them with custom names. For example:
   #   C: 'Do'
   # OCTAVE NUMBER will take on values as the zero-based index of the octave to which the current note belongs.
   # By default in minecraft the first octave (index=0) will contain the first 12 notes from F#0 to E0. The second
   # octave (index=1) will contain the next 12 notes from F#1 to E1. And the last octave (index=2) will contain
   # the last 24th note F#2.
   # It is not always convenient when the octave starts with F#. It is more usual when the octave starts from
   # the note Do. To redefine the note from which the octave will begin, you can use the "base-octave-at" parameter.
   # The base octave (one-lined) will have an index of 0. You can also change the display of the index itself.
   # To do this, use a parameter of the form "octave[n]", where instead of "n" substitute the desired index.
   # For example:
   #   octave[-1]: 'small'
   #   octave[0]: 'one-lined'
   #
   # 2. Formatting for sharp tone notation.
   # This method has a higher priority than the "Basic formatting" and is used when it is necessary to define
   # individual sharped notes within an octave that have their own notation. In this case, the note construction
   # scheme will be as follows:
   #   note-prefix
   #     tone-prefix + SHARPED TONE + tone-suffix
   #     octave-prefix + OCTAVE NUMBER + octave-suffix
   #   note-suffix
   # SHARP TONE will take on the values specified by the parameters "C#", "D#", "F#", "G#" and "A#". For example:
   #   A#: 'Si bemolle' # instead 'La diesis'
   # OCTAVE NUMBER has the same meaning as described in "Basic formatting".
   #
   # 3. Formatting for fully qualified note notation with octave.
   # Finally, you can define a format to display a specific note in a specific octave. This method has the highest
   # priority and is used in exceptional situations. The note construction scheme will be as follows:
   #   note-prefix + FULLY QUALIFIED NOTE + note-suffix
   # FULLY QUALIFIED NOTE will take values that will be determined by the parameters in any of the following forms:
   #   "F#0" - where "0" - is the zero-based index of the octave.
   #   "note[0]" - where "0" - is the zero-based index of the note.
   #   "[0]" - where "0" - is the zero-based index of the note.
   # For example:
   #   C0: 'Middle Do'
   #   C#0: 'Do Fa at the base (one-lined) octave'
   #   note[12]: 'Fa diesis at the base (one-lined) octave'
   #   [24]: 'Fa diesis at second (two-lined) octave'

This is a beta version of the plugin. Please, find and post on Issue page (NOT IN COMMENTS) any bugs, bugs in documentation (my english is not very good), other comments and suggestions, as well as translations into other languages (in the form of configuration files). They will be taken into account in the new version of the plugin.
Source codes will be published on github after the first final version of the plugin is released.
