Leonard Cohen
Most pages that answer this give you two notes and stop. Two notes are not the answer, because the hardest thing about a song is almost never its highest note: it is where the melody spends its time. "Hallelujah" tops out at C4, but it lives between C3 and G3, and that second pair is what decides whether you finish the song sounding like yourself.
Can you sing it?
We know what "Hallelujah" asks for. We do not know what you have yet. The range finder measures your lowest and highest note in about a minute, then this page names the key that fits you.

Full range

17 semitones, about an octave and a half. These are the notes the song requires every time.
Tessitura
C3 to G3
Where the melody actually sits. This is the number that decides comfort.
Original key
C major
As recorded. Transposing is normal and not cheating.
The same song as the Buckley version an octave down, which makes it a completely different problem: staying audible and connected at the bottom.
In folk, that shows up as a specific technical problem rather than a general "sing better" one. Low-range tone and support, where most singers lose volume rather than pitch.
If the song does not fit today, the fix is usually a key change rather than a training plan. Transposing is what working singers do, every night, and a song delivered well in your key beats a song survived in someone else's.
The skill this song is asking for is low-range tone and support, where most singers lose volume rather than pitch. Our curriculum trains that in the tone track, and the daily session will put it in front of you when your voice is ready for it rather than when you happen to search for it.

Slide through the break instead of jumping it.
About 3 minutes. The microphone is optional: with it on you see your pitch; with it off you still get the full exercise.
What is the vocal range of "Hallelujah"?
G2 to C4, about 17 semitones. The melody spends most of its time in a narrower band, C3 to G3, which matters more for whether you can actually perform it.
Is "Hallelujah" hard to sing?
The same song as the Buckley version an octave down, which makes it a completely different problem: staying audible and connected at the bottom. Difficulty is relative to your voice rather than absolute, which is why the tool on this page compares the song against your measured range instead of giving everyone the same answer.
What key should I sing it in?
The original is C major. Whether that is right for you depends on your range: measure it with the free range finder and this page will name the key that fits, including how many semitones up or down that is.
Is transposing cheating?
No. Keys are chosen for the singer who recorded the song, and professional singers move keys constantly, including on their own material as their voices change. Straining through a song in the wrong key is the only mistake available here.
These numbers are our estimate from the original studio recording, not a measurement from a rights-holder score, and live performances of this song vary. Treat them as a starting point accurate enough to pick a key, not as musicology. What we can measure precisely is your voice: the range finder is free, takes about a minute, and needs no account.
