First I downloaded all rock and heavy metal YouTube covers of “Phantom of the Opera” songs. The rock one sucked (too slow) so I stuck with heavy metal.
I used https://tunebat.com/Analyzer to determine the keys and then batched them into folders. This was the breakdown:
A minor – 2 covers
2 songs both instrumental oriented with Lindsey Sterling and super loud interpretted heavy metal version. With double beat bass pedals. No vocals.
It might be interesting to superimpose those on top of each other since they are in the same key. BPM is 69 and 78. That shows some potential.
E flat Major – 5 covers
I didn’t like the Nightwish cover. Too exaggerated of female voice. I had it in two different keys and neither impressed me. So I dumped these.
The remaining 4 covers in E flat Major are all 132bpm except one which is 135bpm.
All intros sound the same. One turned out to be a duplicate. So three remain.
E flat Major-132bpm- Phantom Of The Opera- Rock Style.mp3
Female and male – he is too gritty and she is airy. The music is stylized and dramatic and blasting.
E flat Major-132bpm- The Phantom of the opera (rock cover) – Special guest Sallie Jönsson.mp3
Very clear female part. More dynamic. Guy is gritty but clear. She’s better than her. Guitar solo.
E flat Major-135bpm- PHANTOM OF THE OPERA ROCK VERSION.mp3
Soft violin and cello intro. Don’t like the female vocal lisp. Make a stem of the intro instrumental maybe. Change tempo to match 132. Hate the vocals on this — like the music.
These all sound pretty Karaoke. Ordinary or poor covers. Weak.
F major covers
F major – 120bpm- Phantom of the Opera (ROCKMETAL COVER) Cristina Vee feat. Jonathan Young.mp3
A real good one. Good vocals and instrumentals.
F major – 81bpm- Impellitteri – Phantom Of The Opera (Official Music Video).mp3
Classic ripping metal guitar harmony shredding. Way to fast. Double pounding bass drum. Junked it.
Other covers
B flat major-107bpm- Phantom of the Opera – The Point of No Return (METAL COVER) Jonathan Young ft. Malinda K Reese.mp3
Pretty good cover. Used it.
C sharp minor-114bpm-yt5s.com – Phantom of the Opera (METAL VERSION) ~ Jonathan Young cover ft. Malinda Kathleen Reese (128 kbps).mp3
Very dramatic intro but feels slow. Female strong vocal. Male creepiness but strong.
C major– 123bpm-Y2Mate.is – Phantom Of The Opera Metal.mp3
Not a good band recording. Nice female vocals. The mix is not good. Male vocal weak. Junked it.
CANDIDATES DECISIONS
1. Dump all the E flat Majors.
2. Use F major – 120bpm- Phantom of the Opera (ROCKMETAL COVER) Cristina Vee feat. Jonathan Young.mp3
A real good one. Good vocals and instrumentals.
3. Combine the two A minor instrumentals into an intro.
4. B flat major-107bpm- Phantom of the Opera – The Point of No Return (METAL COVER) Jonathan Young ft. Malinda K Reese.mp3
Pretty good cover.
I then added two DUNE composites — one overlaid with transparent Alpha channel on top of the other. One was too long and I had to double the speed to fit the time length.
