What key is "Once" by Pearl Jam in?

Our song key finder algorithm has predicted that the key signature for "Once" by Pearl Jam is most likely G Minor (Relative key B♭ Major ).

How did the system arrive at this decision?

Besides checking what notes are heard in the song, it also checks for repetition and patterns associated with chords and scales. It also detects the best suited root note so further predict the mode.

How does the system determine level of accuracy?

The sample set of notes can determine how likely of a correct decision is made. If the system is unable to detect many notes, then it is least likely to make a likely prediction. Some of these factors are true of professional musicians too but humans can 'feel' correctness through ear training. Too many notes on the other hand is equally difficult and will result in too many possible predictions. At which case, the system will then average out for the more likely result.

What other factors can affect results beyond the discovered notes?

Ironically the human element can be the biggest impact on the accuracy! Musicians generally stick to the music theory but there's quite often notes misplaced or added based on artistic principles. Perhaps the additional notes can unexpectedly change cadence to the song or the entire key signature could change. Once again, professional musicians can ignore these elements when working out how to play a song, something that AI can quite often misunderstand.

What notes are in "Once" by Pearl Jam?

The system has detected the following notes in Once: D, B, A, A♯/B♭, F, C, F♯/G♭ & E, the most common note being G.

Description

The notes discovered do not apply to singular instruments but all detected notes. Each count of note determines the likelihood of the closest signature match along with best chord based on common and repeated patterns throughout the song.

Key Signature Matching

Below shows the AI using the notes provided to predict the closest key signature. If there is not enough notes to correctly identify the key signature, the system will re-organise the notes then re-attempt to suggest the best match.
