* Lyres don't have a fixed note system: Lyres are ancient instruments, and their tuning varied greatly. There wasn't a standardized set of notes like a piano or guitar.
* "Porque" is a word, not a melody: It's like asking for the notes of the word "cat" - it's just a sequence of sounds, not a musical phrase.
To make this a more musical question, we need some context:
* Do you want a melody using the syllables of "porque?" If so, we can create a short melody based on those sounds.
* Do you want the notes that would represent the vowels in "porque" as pitches? This would be a very abstract concept, but we could assign pitches to each vowel based on some kind of phonetic mapping.
Please clarify your request, and I can help you find the notes you're looking for!
