Audio Implementation & Source Attribution:
  The audio sequences and melodic themes integrated into this device have been 
  independently programmed and originaly implemented for this product. To ensure
  legal compliance and transparency, the origins of these sequences are disclosed 
  as follows:

  1. Public Domain Works: Melodic themes derived from historical compositions 
  (including works by Ludwig van Beethoven) and "The Public Domain Song Anthology"
   (2020). According to the sources, these original works are free of copyright. 
   Furthermore, all modern arrangements from the Anthology are utilized under the 
   CC0 1.0 Universal Public Domain Dedication, where authors have waived all related rights.

  2. Independent Derivation: All digital representations (pitch, rhythm, and duration) have 
  been manually transcribed and modified from public domain scores (including references from 
  Wikimedia Commons) to ensure technical compatibility with the hardware. No third-party MIDI 
  files or proprietary digital recordings have been used.

  3. AI-Generated Content: Specific sequences have been developed using Artificial Intelligence 
  tools. These sequences are utilized for functional purposes and, under current regulations, are 
  considered free of individual copyright claims.

  Disclaimer of Liability: This musical content is provided "AS IS". The company
  disclaims any express or implied warranties regarding the copyright status of these 
  melodies outside the United States. The user or distributor assumes all responsibility for verifying 
  local intellectual property laws.
