Does anyone know of a nice Ap that allows someone to do simple Comp Charts? Basically just Lyrics with Chord Symbols above?

This is great program ( albeit somewhat pricy for my pocket book )that automatically detects chords (tablature form for string instruments ) in the song when you load it.
That helps me learn to play the song even though I do not play guitar.

Slowing down and changing pitch is helpful in hearing the effects at different speeds and pitch before deciding how to score the music.

I do not like it, costs too much to upgrade periodically.

There’s a big difference between Capo and others, the point is it allows me to listen to a song at a pace that I like, so the good thing will be I can learn to sing a song and meantime to do that in an unfamiliar language. Love it.

Correcting a comment someone made below:

you can drag a tune from iTunes just fine.

It just doesn’t get dragged into the usual launch window, it has to get dragged into the blank window intended for this.

As a music teacher, I've been transcribing musical solos for over 25 years and I have to say I love this program. I just upgraded from version 2 and version 3 adds a few bells and whistles that make it a more polished product.

Pros: Fast, easy to use, built-in vocal reduction, built-in speed and pitch changes, chord recognition, an all-in-one solution for transcribing songs and solos.
Cons: Chord recognition isn't perfect, a bit pricey for the hobbyist, can get a little glitchy at extreme pitch or time changes.

For me, this is a great for teaching and also for figuring out those really tough solos. Another reviewer pointed out that it wasn't accurate for detecting chords but that's a tall order since the same group of notes can technically be more than one chord. Add to that a moving bass line and other instruments playing different inversions and even a human will have some trouble from time to time detecting the correct chord.
And as others have pointed out, you can do pitch changes and time changes in Logic and other audio programs (if you own them) but having all the tools optimized for learning makes this a faster solution. I used to bounce songs between two audio editors and now I just use Capo. It also looks like the developers are always tweaking the software and adding features so I can't wait to see how Capo improves over the next year. This is a must have for serious students and music arrangers and educators.

I don't know what all the fuss is over this program. The "demo" lasts only 10 minutes! The chord identification failed miserably on a popular song with an orchestral background. And I mean _miserably_. The orchestration had some augmented fifths and sixths and, apparently failing to identify them, it just started making up simple chords like Em etc. So I tried a clean recording of one of my own songs which was only an acoustic guitar playing strummed chords and a simple, one-note lead. The piece contained some jazz chords. It identified Cmaj7 as Em and completely punted similarly on things like Gaug7. So I tried it on a simple three-chord song (Buck Owens' Cryin' Time). It correctly identified the chords that are in the song (I, IV and V in the key of Ab) but missed numerous transitions and the ones that were correctly identified were frequently displaced in time, according to the cursor position.

I did have a chance to try slowing down the music, and that part seemed to work well.

Maybe I could work something out with this program if the trial period were longer than 10 minutes, but phewy on the whole thing. :-D

Oh—I forgot to mention that dragging a file from iTunes to the program's window does not work; you must locate the file in the Finder and drag it from there.

Please ensure that you have the latest version! The dragging issue was related to a combination of sandboxing and iTunes music located outside of the standard ~/Music folder. We've fixed this since, and thank everyone for their feedback!

Awesome Tool! Great UI! Does exactly as advertised and has a modern and clean look & feel. Cool 1min explanation videos in the startscreen. 5 Minutes and you're good to go. This is the best guitar learning app I have ever seen!

Whatever I try to slow down, the time stretch algorithm seems to be glitchy. For some minor slowdown it has no or less artifacts but more then 10% slow down is bad quality.
I understand it is hard to compete with the pro timestretch algorithms from for example Logic or Cubase (Warp is amazing btw) but the high asking price demants something that sounds better imo

You know, I never think about using Cubase to slow down fast musical passages so I can learn them! Duh! I've been using Amazing Slow Downer even though I have Cubase 6. Good suggestion.
