Author: oh, I see. Then I need to do something there too. It is pretty much the same problem and the same solution. Right now, for efficiency reasons, for the Parsons Code, I do a preselection based on what is most similar to the first couple of characters, and calculate the actual distance only for that preselection. Because of this, there is more weight on the first character than there should be.

Well, for whatever it's worth, I generally use the Parsons code to search for melodies, as I did in this case. I did not attempt to use any of the other tools on this site. I hope that helps you track down the missed search result.

This is already in Musipedia, thus it's peculiar that "search Musipedia for this" doesn't find it ... Perhaps because your sample is longer than the one stored in Musipedia, and the search does not allow for a "truncated" match?

Looks like the latest changes in the search algorithm made it a bit too sensitive to a single mismatching note (see what happens if one omits the first note: http://www.musipedia.org/search.0.html?sourceid=melody-url&tx_mpsearch_pi1[submit_button]=Search&onlymatchfrom=0.3&categories=CPAH&tx_mpsearch_pi1[pc]=hum+0.5-60-0.5%2F1-60-0.5%2F1.5-60-0.5%2F2-60-0.5%2F2.5-59-0.25%2F2.75-60-0.25%2F3-62-0.5%2F3.5-60-0.5%2F4-59-0 ).
Well, I already know how to address this. Right now, for the pitch component, I search for nearest neighbours only in the subspace with the same dimensionality (same number of notes). I need to tunnel across subspaces to be able to tolerate mismatches like this and still recognize the similarity apart from one note that does not match.

I can't place this tune, although the melody is extremely familiar. Here's as much of it as I could remember well enough to enter here... if anyone out there knows the name of the piece this melody is taken from, please enlighten me. Thanks!

How to insert music:
Add a bit of sheet music, along with a MIDI file, simply by entering note names in Lilypond syntax between the [L] and [/L] tags.
For example, you can try what happens if you enter: [l]g'4 g'4 d''4 d''4 e''4 e''4 d''2[/l] (use the Preview function if you don't actually want to post this).
You can create these lists of note names by clicking on piano keys here.
How to post an audio recording:
If you just want to sing, whistle, or play a melody so that other forum visitors can hear it, follow these steps:
- Record your audio here.
- You should notice a 32-character hash code, something like: 2a40281c5001c5a7d8c9f57fcdeccfaf
- copy this hash code and paste it into a forum post, enclosed in the audio tags, for example: [audio]2a40281c5001c5a7d8c9f57fcdeccfaf[/audio]
How to mark a thread as solved:
If the original question in a thread is solved, please mark it as solved using the "solved" icon (or by just typing [solved] into your post). This makes life easier for people who are willing to identify melodies, since unsolved problems are easier to spot that way. If a problem turns out to not be solved after all, just write [/solved] in a new post, and the thread will be labeled accordingly.
