dynamically track and publish records of folk music playing It captures, stores, and posts the names of tunes played in Irish traditional music sessions on a public website Disambiguate between noise and music based on spectral flux Tunes were annotated based on majority voting of several 12 second samples 20-50% accuracy , longitudinal statistics) of tune playing practices, the changing repertoire of a session. to examine whether instrumentation of traditional and folk arts is and should be possible Semi structured interviews and less formal during session with anchor musicians At the same time, TuneTracker seeks to respect the privacy of musicians by not recording or streaming any actual audio. Deployed for five months in Dublin, Ireland at The Cobblestone pub Amateurs can intelligently practice certain (e.g., most popular) tunes in a session. Professionals will be able to reflect on the repertoire of their sessions. TuneTracker is also an academic exercise in intervention
Some of the anchor musicians of a particular night requested that we turn off TuneTracker during their session time semi-structured  interviews (N=7) and less formal interviews during session observations (N=4) with anchor musicians. In other words, TuneTracker is imprinting on amateurs a deterministic image of what a session is—that it follows a formula One anchor told us he received a text from a friend saying “I see you’re in The Cobblestone tonight from the tunes that are being played.” Through the tunes, the musicians were being tracked.
When seeing the low percent of polkas (3%) in her session, an anchor told us, “Now, we’ll have to do something about that!
I don’t think technology should be pushing the music. I think the musicians should be pushing the music...It’s a bit [like] a genie out of the bottle though.
In the second quote, the musicians see TuneTracker as a tool, not a substitute for the tradition. For them, any artifact that can encourage more people to play and reflect on traditional music, thereby preserving the tradition, is beneficial. TuneTracker will encourage visiting musicians to join in sessions.
TuneTracker has agency —it deliberately introduces a power asymmetry  by wresting control of sessions away from the musicians and into a technological artifact. TuneTracker will be prescriptive: spelling out what tunes people should demand in sessions. Because TuneTracker is authoritatively clothed in digital garb, it asserts itself as the final truth—whether it be regarding tune names, tune notes, the order of tunes in a set, etc. Thus, TuneTracker threatens to destroy tradition by marginalizing the human element in the traditional process Just like any resource (e.g., sheet music), it can be misused

2 of the challenges that were taken on my Pierre Beauguitte in 2015 Approaches these problems with great academic rigour Coming the completion of his PhD

Similar work done by IZZY Co supervising 5 years of outstandiung scholarship to bear on these problems 30 tunes Foinn Seisiun´ books published by the Comhaltas Ceoltoir ´ ´ı Eireann ´ organisation, available with Creative Commons licence. These offer good quality, homogeneous examples of the heterophony inherent to an Irish traditional dance music session. • Grey Larsen’s MP3s for 300 Gems of Irish Music for All Instruments, commercially available. These consist of studio quality recordings of tunes played on Irish flute, tin whistle and anglo concertina. • personal recordings of the second author, a renowned musician, on the Irish flute. These are available together with the annotations.
Tony software . After importing an audio file, Tony offers estimates using the pYIN algorithm (notelevel) presented in the next section. These were then manually corrected, by adding new notes, merging repeated notes and adjusting frequencies. The annotations were finally post-processed to convert these frequencies to the closest MIDI note references Exported to CSV files
a note is considered correctly transcribed if its onset is distant from the reference note by less than 50ms and its pitch by less than a quarter of a tone
Precision, recall and F-measures are computed with the mir eval framework It is interesting to observe that MATT achieves the highest F-measures on the solo recordings. However, only the difference with Silvet is statistically signiﬁcant On the session recordings, Silvet achieves signiﬁcantly higher pitch precisions Why?
musical key consists of a tonic note, represented by a pitch class (C, C#, D...), and a mode, or rather mode family, which can be minor or major 24 candidate keys, for the 12 semitones of the octave and the two considered modes The standard approach to identifying keys in a musical piece is to use key-proﬁles They can be seen as vectors assigning weights to the twelve semitones The paper compares different approaches to generating keyprofiles from the literature with two new approaches introduced by the author based on CADENCES and modes in traditional music Pierre annotated an audio dataset 636 items from the fionn session tunebook, Grey Larsen’s 300 gems, also a symbolic dataset drawn from thesession.org Ran an experiment which extracted the pitch class histogram from the tune in audio or symbolic format Audio files used deep chromas Key was evaluated by comparing against the 24 key profiles one for each semitone. Cross product Highest score
Hence it appears that inferring keys from heterophonic or polyphonic audio is easier than on monophonic recordings. An explanation for this is that the harmonic content is richer in heterophonic and polyphonic signals. Cadences outperform the existing key profiles Propose an improvement by adding weights 10 fold cross validation is used to estimate the size of a grid search to evaluate the optimum weights Using the evaluated weights Pierre is able to improve the mirex score again Parametric profiles
Two new types of error neighbour key errors and relative key errors. The high frequencies of these two types of errors can be explained by the speciﬁc characteristics of Irish traditional music minor keys are harder to detect than major keys The key annotations on the datasets were made by the ﬁrst author, and it is possible that other annotators could annotate some of the tunes differently Ambiguous

Pitch class histograms are generated for the symbolic audio 120 valued vector. A Gaussian kernel of size 150 cents . The vector is normalised to sum to 1. Makes the representation close to the audio one Audio PCH STFT, summed, 120 valued vector Aligned using Bhattacharyya coefficient. Select the shift that has the highest score that provides the best alignment these symbolic PCH can be pre-computed. Once this optimal shift k is found, the symbolic quaver sequence is transposed by round(k/10) semitones, as the unit for k is 10 cents

QbSH tMIREX Top-10 hit rate (1 point is scored for a hit in the top 10 and 0 is scored otherwise) Best (Top 1) Hit rate a new way of ranking is now introduced worst possible rank (WPR) worst possible rank (WPR), is a way of ranking results that appropriately deals with draws Relative difference? Original with a tip – glass ceiling All – Go through all possible semitone transpositions and pick the best – brute force
PCH to the best a novel approach. Existing literature has often focused on audio-to-audio alignment in the context of cover song identiﬁcation (EllisandPoliner, 2007;Serraetal.,2008), or has relied on keyannota tion when dealing with symbolic music The method introduced here performs audio-to-symbolic alignment without the need for key annotation, thus alleviating the difﬁculty of deﬁning key in ITM Without reducing accuracy and by adding 50% to the tune identification task compared to 12 times more for the brute force approach

Listening to ClareFM.ie this morning.
Heard a great tune…..interrupted by the Galway Races Used Tunepal……..it’s called The
Parting………got it from The Session.org. So much fun……….. listening and learning Irish Trad.
Thank you so much for the good you have done and are doing!
It is ironic, but one of my mates has proudly proclaimed she has never had a cell phone,
computer, nor opened an email account. She is utterly fascinated with Tunepal
“I’m sure you’re getting emails every day saying how much folks love your tunepal site and
iphone app. I have the app and LOVVVVVVVVVE it! I use it every day. Awesome awesome
Getting a lot of use out of this app now. Everybody I have told so far is very impressed.”
It’s pure magic. Thanks a million for having made this diamond and share it with everyone. If
there was a God, I’m quite sure that he would have you blessed !
I just wanted to thank you for the great idea and the great job you’ve done with Tunepal. It’s an
excellent and very useful tool. Just what I whished for quite often.
I am really impressed with the app. It was 100% correct in identifying tunes when I played them
on flute or whistle. Having worked in a previous life in ultrasonic testing of materials, I can
appreciate some of the problems involved.
Thank you, Tunepal!!! You’ve saved lives!!!!!!
Fair play to Bryan it’s a wonderful App I have learned lots of tunes from
it and Names of Tunes as well
Amazing! Congrats! I must be at least 30k of the tune searches 🤔☺ I use
it so much. I love it
