The rock group "Aria" is so popular that it can be safely attributed to classical music in the broadest sense of the word (lat. Classicus - correct). Based on the meaning of the word, their music can only be played correctly and only in the way that music lovers are used to hearing it. But there are exceptions.
Instructions
Step 1
A performance by one rock group of a song of another collective is called a cover or a cover version. The cover retains the main instrumental composition of the original, adds instruments that the authors did not have or excludes parts of instruments that are not available for the performers of the cover.
Step 2
It is not difficult to get sheet music or taboo recordings of songs. Sources include piano-sheets.ru, amdm.ru and many others.
Step 3
The parts must be learned by heart and performed without hesitation. Just as classical lovers hear the slightest deviation from the original text by the performer, so in rock music you will not be forgiven for rhythmic disturbances in the riff that fans have been listening to day and night. This is especially true for the vocalist. Both Kipelov and the current singer of "Aria" Dubinin have a good vocal school, the falsity or meager abilities of your singer will be very noticeable.
Step 4
You can customize the original by changing the arrangement of the song. For example, "Aria" did not have a keyboard synthesizer. If your team has it, then from any song you can make both the most tender lullaby and a bravura march or an action movie that breaks through the listeners to tears. The main thing is to show your imagination and leave the basis of the song intact.
