Everything there is free, but what you download is somebody's own
interpretation (or arrangement or whatever) of the song that they've
uploaded and allowed to be distributed.   It's just the chord chart or
tablature for guitars.   It's not copied sheet music and it's not a
recording of the original work.

It's really useful, though, if you want to learn a song.   Often there
are three or four versions of the same song submitted by different
people, sometimes with varying degrees of difficulty.   There's a
format that is used that allows the user to change the key if desired
before printing/dowloading the song.   I use that a lot.

Seems to me you might do this under fair use. It would have to
be a small enough part of the whole.

Exactly what you can do with fair use is always a question.
Shazam, after identifying a song, will offer you a site that
you can buy a copy. That should make copyright owners happy.

Maybe even enough that they would pay Shazam.

I don't know copyright law enough at all to know if the Shazam
database would be at all considered copyright infringement.

Chords seem somewhat less obvious.

Do they offer to sell you a copy?

There seems to be some grey area escape route on some of this.   I use
a site called chordie.com which has a very large library of songs for
guitars, either chords or tablature.   There are usually disclaimers
that the submissions are essentially 'reverse engineered' and
submitted by individuals rather than copied directly from somewhere
else.

Chordie is huge and a great resource, btw.

Hmm, I could be wrong then, I was just assuming that if the software is free they must not be paying any royalties. It's hard to imagine that you would need to pay just for the chord progression.

that surprizes me, Bob.  there are other music-y services/product (ujam, 
zya) that provide just the accompaniment (and short snippets at that), 
no melody nor lyrics, and one of the big money issues for at least one 
of those two is licensing.

"Imagination is more important than knowledge."

A popular software package is called iRealb. The user group site has thousands of songs, virtually every rock and jazz tune you can think of, and it can play the chords for you using midi. It only provides chords and not lyrics or melody; this allows them to get around any copyright issues.

I've seen a keyboard player using an iPad to do exactly this. I have no
idea what software he used, but it seemed to work quite smoothly as he
played.

I suspect this is one of those problems where its fairly easy to put a demo
together, but really hard to make something robust enough to be genuinely
useful.

I use SoundHound, and my friends and I have had competitions to sing songs
into it and see if it can get it.  It usually can figure it out.

Note that Shazam does an exact match. 

It can only match the exact same original recording. 
Anyone else playing the same piece and it won't match at all.

Still pretty neat, as it has to be able to do it with noise and
some speed offset.
