Processing Piano Tutorial Videos in the Browser

I'd filter piano tutorials based on interesting music. Playing jingle bells (as in my first piano book) isn't exactly motivating. I guess this especially holds for older people who have already acquired a certain musical taste.
tangue•5mo ago
This is really a great idea. While fancy these piano tuts are quite useless compared to something like guitar tabs. Hope it will improve
thimabi•5mo ago
Great idea and execution, congratulations!

I used to learn songs from piano tutorials like these, too, and had to do the manual work of annotating keys and chords. It’s nice to see a very real pain point being eliminated — maybe I’ll even find some new songs to learn :)

catchmeifyoucan•5mo ago
Hooray! Yeah, give it a try.
vunderba•5mo ago
I'm VERY familiar with Synthesia. In order to generate those animated videos of falling notes, a corresponding MIDI file for the song has to exist. I would think it'd be better in most situations to build the purported "piano tablature" off of that instead.

While neat from a technical perspective, this seems like a solution in search of a problem.

EDIT: On the other hand, a cursory search did not find any midi/piano sheet music for "Hi Nanna: Samayama" - so maybe only having this "falling note video" is more common for certain music.

catchmeifyoucan•5mo ago
Oh yes, there's a lot of songs that are published in the tutorial video format, but the MIDI source isn't shared.
bcowde•5mo ago
I really like the idea of being able to import tutorial videos into a tab-like format. I have a tool which puts tabs into browser storage and displays them (https://pianoboi.site/) - It would be really cool to provide an import feature from your app.
catchmeifyoucan•5mo ago
Oh I love this. And it'd be really cool to see that.

The current output isn't a particular format. It's purely text output that looks like this.

1:01 -----|A1--B1|----A3--A4|

1:03 -----|A1--B1|--A3--A4|---B2|

If you had a way to copy and paste that as a string of notes and visualize in a loop or some-how that might work. You'd have to figure out how long a note was pressed etc, so it may require some extra logic.

I use Onsets and Frames to import youtube videos into my piano practice software. It works like a charm and I'm quite impressed with the accuracy of the transcription. I really don't like the 'piano roll' style software because that's just not how music is represented in a logical way. Compared to regular sheet music it is a pretty poor medium.
