Bad key information or I'm missing something?

[FarleyCZ]

I was wondering how many of today songs are in minor keys. So i searched in todays music and found out that acording to musicnotes.com and e-chords.com is B.O.B's Airplanes (btw great song) in F#minor. But it was wierd, becouse I jammed to this song in some major key and it sounded right. So i found a tutorial: And it's in the same key I jammed to it. Amajor. (or at least guy plays it on notes belonging to Amajor)

Question is: Is it bad key information on that sites, or my hearing is bad and man on YT transposed it accidently to key I jammed in or I miss something?
...i can imagine it is F#minor with some notes switched, so it looks like Amajor ... but it doesn't make sense to me....

all minor keys have relative major keys (and visa versa). That means the notes are the same. F# minor and A major are the same relative key, (same as C major and A minor, all white keys). The difference between using the major vs. minor key is which note you treat as the root note.

I don't know the song, but I'm guessing it is F# minor, but you are playing the notes thinking, these are all A major keys. If you pay attention to which note is actually the root note, it may be F#. (If F# is the root note, every thing should sound like it wants to eventually return to the F# minor chord)

Thx! Yes, friend told me this once, but still problem here:

Wait! There is that Pure minor option which works as you said. So now the question is: What's difference between their pure minor and minor?

I kept it simple in the first explanation, but you are right, they are not exactly the same. Minor keys have melodic and harmonic variations that major keys do not (pure minor is exactly the same). Playing the minor key variations in a song that is actually in the major key will sound off, out of tune. However, since the major key does not have such variations, playing the major keys in a song that is actually in the minor key will sound fine. Which is why you could play what you thought was A major in a song that is actually F# minor.

And I suppose that's why my Xzibit remix, when I changed key of song from Bbminor to Bbmajor seemed to me a little wierd sometimes. I thought it was in some variation close to Bbmajor. But proper change would be to C#major I suppose.
Btw as we are talking about that, do you think you could listen to it and say if it's any disrupting? http://www.indabamusic.com/submissions/show/25750 noone noticed something wrong, but it still didn't fitted exactly to my ears. I don't want you to vote (but I'm not gonna be upset by that ), just take a listen and tell me how much big mistake this change was if you could.

the sixth and seventh degrees are variants in minor other than natural minor.
F# G# A B C# D E#, is known as "harmonic minor". That "E#" is derived from the "Dominant" harmony, "V", spelled here C# E# G#. The scale in accordance with that harmony takes that raised seventh degree, which is a "leading tone" to the "tonic", hence "harmonic minor".

Once upon a time you appeared to be wicked if you fooled around with that D E# bit, *augmented second* (like you went all Arabic I guess), and (in other related religious sort of thought) it was deemed worthy to do "D# E# F# " instead of... that came to be known as the "rising melodic" form. The "falling melodic" preference lowered both degress, here: E D (C#...). Basically for the ever-popular smooth, non-disturbing to Mother Mary and Joseph effect.

Jazz musics in some cases uses the so-called rising melodic form in both direckshums, and there is theory which has that intervallic structure as a basis for other modes.
Your natural minor may be considered as a mode of 'major', ie., the same 7 intervals in 7 different sets.

As far as I recall, that song doesn't use the root of the chords in the bass, that could be the confusing part.
