What we already told, -metadata is the option. You can specify the
option more than once, e.g.:
ffmpeg -i clasicos.mp3 -ss 00:00:00 -metadata title="Chapter 1" -metadata author="John Doe" -acodec copy -vcodec copy clasicos+tag.mp3
And metadata is a global property of the file/stream, you can't place
it in "several parts of the audio" if I can understand you correctly.
You can check the tags in the output file with ffprobe -show_format FILE.
Note that your commandline is wrong, as you can't have the same file
both as input and output.
