You are supposed to listen to the second line and tap the rhythm that you heard on the fourth line.

You listen and then you tap - has to be exact - like you are playing a drum. Get the beat in your head and count

It is impossible to tap those fast rhythms on a keyboard. Just don't worry about it too much.

Actually I think that it is possible . Rhythm is exact and is such an important part of music. IN Rhythmania get the rhythm in your head and dont pay too much attention to the on screen prompt that is beating out the beats if you wait for it you will always be behind. Feel the rhythm and just tap it on the space bar

Is it possible you are attempting to tap the metronome along with the beat you are supposed to duplicate?

@IAN TANG: I am at level 121 of Rhythmic Parrot and only once have I encountered a beat that I thought was impossibly fast, and that was fairly recent (definitely at a level higher that 100).

I would quibble a bit with what Kathy said about not paying too much attention to the on-screen prompt. While I agree you certainly don't want to wait for it when tapping the rhythm, I find that while I'm LISTENING to the rhythm, creating a visual connection with what I'm hearing by watching the animation closely improves my retention of the rhythm. Taking in different but connected bits of information is a good way to reinforce memory.

Victor, I do think it's something to do with my tapping on the wrong line, but even if I only tap to Line 4 I get the same result. We're talking about a simple 4/4 rhythm and so it's not my ability to replicate it, but I am doing something wonky. Is there a tutorial somewhere that I haven't seen? I can be oblivious about finding help features!

Just to be clear, I was not talking about tapping on the wrong line, I was talking about mistaking the metronome pulse for part of the rhythm you need to replicate. I am just trying to think of possible explanations for it registering too many taps. For instance, I've never seen that issue myself unless I actually tap too many times. :)

Another possibility is that you are holding down the space bar long enough for it to repeat spaces -- a keyboard does auto-repeat. I could see that being an issue with slower or more sparse rhythms. If you suspect that might be the case, try a sharper tap to the space bar, or check the auto-repeat settings on your computer.

I'm in the same boat, on mobile though.

I do not understand when I am supposed to tap. I always get too few or too many taps. I have not got the game to recognise my input as valid even once. Extremely frustrating.

In the case of rhythm parrot, can someone tell me on what line I should tap?

I could not get Rhythm Parrot to work at all on my iphone! As far as I can tell, we should be tapping on the last line. So far for me, sometimes that's the 2nd line; sometimes the 4th.

Tonight instead of the message that I was tapping too much, I was told I was inaccurate. Seems like progress to me!
