Is it good to learn piano as a beginner with labelled keys

oh yes it is!!

Explanation:

as an ''adult'', remembering piano keys, violin tabs, flute notes and etc between doing schoolwork, and following your schedules will be very hard so i advise you , please add labels to your keys if you're a beginner

( even as a pro at piano, i still use labeled keys to play songs )

they most likely have a instrumental version. just look it up on google.

the answer is counterpoint.

counterpoint definition: "the art or technique of playing a melody or melodies in conjunction with another, according to fixed rules."

counterpoint is present in a lot of baroque music- such as bach (notably his wtc prelude and fugues) and scarlatti, but can also be found in music by mozart, beethoven. it can even be found in music as modern as john williams!
