Это из-за того, что не была выставлена нотация. Поэтому производилась попытка ее "угадывания" - аккорд Fadd9 распознавался в Spanish-нотации и при конвертации Fa заменялось на F.
Dear "sevier antiquisa" and all who want to save your songs here,
I would like to ask you politely not to fill the database with unnecessary information.
Please copy the songs here without additional information, as well as header or footer.
Additional information can be stored in "Comment".
In case of frequent violations, the songs will be removed.
Thank you for your understanding.
If the capo is to be placed on the second fret, then at least one chord is expected.
It would not be bad if you copy the songs from somewhere at least once trying to play the song or at least control the lyrics.
