In the spirit of releasing things before they're ready...
I've been working on Violin.io (https://violin.io) since 2015. It's eventually intended to be interactive sheet music in the browser synced with YouTube recordings of classical music through the use of music information retrieval (MIR) algorithms. For example, click on the score at measure 50, and you'll get a YouTube video at measure 50, and you can change among different performances of that work at measure 50.
There remains technical challenges, so for now you won't find much yet other than well-tagged and categorized videos of classical works without sheet music. But I'm actively working on it.
You can help. If you frequently listen to or perform classical music, contact me at steve at violin io. I would like to know what specific works interest you. Currently, I'd prefer to focus on strings or piano, and Bach/Mozart/Beethoven/Brahms, and preferably chamber. But I'm open to all suggestions. (I think there's merit to pleasing a narrow audience very well, and with classical music variety being enormous, it can get out of hand quickly.)
I welcome it. I enjoy the challenge of staying focused when I notice out of the corner of my eye a crowd forming or people filming.
Sometimes I cope by playing with my eyes closed. Violinists have options where to position their eyes: on their bow, on their fingers (rare, but helpful sometimes in practice), out into space, or closed. For example, James Ehnes and Hilary Hahn look at their bows, but Itzhak Perlman and many others play with their eyes closed. I focus on the bow, but when someone is taking a video, I might close my eyes to remove the distractions.
Steve here. Indeed, I already play at least four orchestra concerts per year and a number of chamber performances. Busking provides a performance opportunity of a different sort by playing solo music which is more exposed and musically dense.
And yes, you're also correct that for some instruments, concerts are not easy to come by. Our orchestra has a wait list of 70 flutes! Our #1 organizational challenge is figuring out how to provide more performance opportunities to more people in a financially sustainable way.
(Incidentally, I have seen one solo flautist busking in Powell Station. He was a high school student.)
Steve here. That guy is great! Perfect idea for a trumpet. He's always standing on a bench/podium in the northwest corner of Union Square. His sound really projects; you can hear him from inside the 2-Muni bus that rides on Post.
Steve here. Thanks for reading! Those earnings are certainly not sustainable over eight hours in a day, nor over every day of the week. But they are attainable in strategically timed bursts. Some earnings are also skewed by a very few who donate $20.
Doubly interesting to me since I’m thinking of performing as well.
The kind of performance I’m considering, though, would be of a more obscure style and requiring some electronic gear (worth $xxxx), so I’d probably go for a collaboration with a friend at least to have a sense of safety.
Regarding eight hours a day, as a software engineer most days I personally pull off about 5 hours of actual focus tops, though maybe that’s just me.
I think that's a great idea. Electronic aids, despite the overhead, have a higher ceiling than a feeble acoustic violin. It can be more unique, more exotic, and more easily heard.
My focus on software is also 0-5 hours a day, and those hours are only before noon and after 10 pm.
For anyone interested in this area, the IEEE Transactions on Information Forensics and Security (TIFS) [1] is full of papers on the so-called area of image forensics -- the identification of processing that has been performed upon an image, including resampling, rotation, JPEG compression, block processing, and more.
Consequently, another hot research area is image anti-forensics -- the obfuscation of such operations to avoid detection. (Shameless self-promotion: one example paper on anti-forensics of JPEG compression can be found here [2].)
My first experience with Persona was through my mobile phone provider, Ting. They still use Persona: https://ting.com/account/login. I loved it then, and I love it now.
Off-topic, but your article's design looks beautiful. What did you use to generate it, e.g. a converted IPython notebook, or homemade CSS plus MathJax? And what did you use for the figures?
I glanced through the entire PDF. While it looks like an outstanding comprehensive overview to neural networks, it doesn't appear to really address NLP all that much, despite the title.
I would gladly welcome if you or someone could write a guide that has the comprehensiveness of the PDF above but with more NLP domain-specific discussion and concrete examples.
I busk solo violin in San Francisco's Powell Station -- 45 times since January 4, 2014. I last played on September 20 and made $51.02 per hour. My friends have encouraged me to write about my experiences onto Hacker News, but I never have.
You learn a lot about people and crowd dynamics. Donations come in clusters; if a person sees someone else donate, he/she is more likely to. In an attempt to teach empathy, mothers often give cash to their three-year old kid to put in the violin case. The few who drop a $10 or $20 are often over 40 years old.
Twice I've had money stolen, both by dudes in their late teens or early twenties.
Sound definitely matters; you can't just "look good". Busking at the Ferry Building was a bad idea; no one can hear you. I'll never do that again.
High-density foot traffic is not always a good thing. In the evening rush hour, there are so many people obstructing view and making noise that I imagine it's difficult to appreciate the music by the time you've reached the fare gates. I believe that a medium traffic density works best where the sound can travel and there is always a direct line of sight between pedestrian and performer.
Sometimes the "great works" make poor busking choices. The Bach Chaconne is a great example.
Unsurprisingly, an ensemble with more performers earns more than a soloist. On August 20, 2014, we played the Mendelssohn Octet in Powell Station and collectively made $461.64 over 90 minutes, or $307.76 per hour. However, that's $38.47 per hour per person. I make $15-50 per hour solo. So I wonder where the diminishing returns begin, i.e. what ensemble size maximizes revenue per hour per person.
Is it scary? The scariest part was leaving the apartment that first day. Exiting the apartment door was the point of no return. "Okay, I have my jacket and shoes on and my violin, I might as well go on with it." That moment when, for the first time, alone, I plopped my music stand in the middle of Embarcadero Station was one of the most uncomfortable moments of my life. However, once you start playing, that's easy. The music is the easy part.
If you want to busk but are scared, I recommend going at a less busy time, e.g. Saturday morning at 10 am. Get used to the surroundings; embrace your anxiety. Once you're comfortable, try again next week at 2 pm.
Would it be worth it to pay a someone to appear to donate every time a crowd walks by?
I love seeing live performers although it depends on the situation. In Paris the hallways are too small and the buskers are basically blocking the already crowded hallways. In NYC the ones that actually come on the trains and then go around with a hat make me feel uncomfortable although any performer who's really good I appreciate.
I'd also be curious how those numbers change in countries with larger coins. I assume it's easier to give coins? No worries about bills being blown away. Coins "feel" more disposable? There are €2 coins in Europe. There are 500yen coins in Japan (about $5) where as there are only basically 25 cent coins in the USA (yea 50 cent and $1 coins exist but are not common)
Hmm, interesting. Perhaps it is not worth it to "hire" a spectator to donate, but I think simply a spectator to stand around like an audience member can be more effective. That's another thing that often clusters; people who stop and listen. At really odd times, I'll look around and all of a sudden notice five people who stopped to listen.
Yeah, positioning is key. I do not disrupt traffic flow at all; for those who know Powell, I stand at the end of the long hallway on the 4th street side. That gets me a captive audience for about 30 yards. They have no choice but to listen to me on their way to the BART/Muni gates. Acoustics are good too.
Indoors, there is little chance of bills being blown away, but otherwise, I agree with you about coins. $1 coins are actually not that uncommon.
