@xlilkatiex1 If it’s a transcription of an established song and you want to stay true to the sound, realize that there are differences in range and playability between the guitar and piano. What is extremely easy to play on piano might be impossible to “spell” the same way on the guitar based on the string layout and intervals between the strings.
If you’re used to playing the “open” chords of a guitar, it’s not too difficult to use those inversions (spellings) directly on the piano. You could start literally note-for-note transcription, if you know how to identify notes and octaves/registers. Keep in mind that with guitar, you’re playing six strings most of the time in open chords, so if you’re adapting for piano, keep in mind that you’ll need to individually write for six unique notes/fingers. For beginning piano players, this may be difficult to play, especially playing chords in succession and quickly.
It’s an art, not a science…best bet is to write it out on paper, then work at the piano to check the playability. Same goes the other way around with piano to guitar.
