Show HN: Scale Heaven – Browse and play any scale/chord, chord progression
- theflyinghorse 7y agoAwesome! I'll experiment with it tonight. edit: One comment - when I clicked on chords progression it took probably 10-20 seconds to load but there was no indication of loading so I originally thought that perhaps the section was unavailable
- seanitzel 7y agoWow, thats fedinitely too long! Ill check it out :)
- QxeenJasmynne 7y agoFuck this shit you stupid dumb bitch
- tanseydavid 7y agoThanks for this.
- seanitzel 7y agoYour'e welcome!
- tylerscott 7y agoThis is a wonderful app. Also kudos for the Note-Art lib.
- seanitzel 7y agoThank you! :)
- birracerveza 7y agoThis is great! Only two feedbacks: - Sometimes the audio lags out a lot. I know it's probably impossible to get low latency audio via Web Audio API (which I suppose you are using) but yeah. - Dark mode > everything else ever. I would default to it. - I want to donate to you, but Patreon is a turnoff. I'd rather use Paypal or a similar one-time payment option. Regardless, it seems to be an incredibly useful tool. I've been looking for something like this for a long time. Again, thank you!
- seanitzel 7y agoThanks for the feedback! - Yes, im indded using the web audio api, which is unfortunately problematic... - Your settings are saved so you will have to switch only once, but actually i really might consider default to it. - I'll add a one time payment option :) I'm so glad to hear that, i really put my heart and soul into it!
- re 7y ago> Sometimes the audio lags out a lot. I know it's probably impossible to get low latency audio via Web Audio API The Web Audio API lets you trade off how far in advance you schedule things -- so if you want to be able to react to events faster, you can use a smaller buffer, but if you want to ensure that things don't lag out, you can use a larger one. There's a good overview here: https://www.html5rocks.com/en/tutorials/audio/scheduling/ https://www.html5rocks.com/en/tutorials/audio/scheduling/ The only issue with the audio that I noticed is that when playing the progression with the metronome, the metronome timing seemed fairly uneven and also tended to come in slightly before the piano sound. I didn't notice any timing issues with the piano alone though -- are they scheduled using different mechanisms?
- seanitzel 7y agoI'll look into it, thank you. And weird, they are scheduled using exactly the same mechanism.
- sixstringtheory 7y agoCan’t wait to play with the progressions. It’s an area I’ve been looking to improve for some time, thanks!
- seanitzel 7y agoYou're welcome!
- d-d 7y agoI'm getting a blank white page on Firefox.
- gabergg 7y agoThis is really great! For your progressions section, are all of the progressions added manually? It would be cool to have a way to generate or manipulate them more flexibly. I'm the founder of Songcraft (https://songcraft.io https://songcraft.io), an online songwriting platform, and we've tackled some of the same problems. It'd be great to connect! My email is in my profile if you're up for a chat.
- seanitzel 7y agoThe progressions are indeed added manually, I started looking into ways of generating them in a different way but dropped it atm because i'm too busy haha And i mailed you :)
- simmer 7y agoExcited to try this buuuut... on iOS, there's grey touch-blocking overlay over the entire interface with no way to dismiss it.
- chaoticmass 7y agoThis happened to me on Chrome in Linux. I turned off my adblock and the grey overlay went away.
- seanitzel 7y agoAlso, it's a pwa so you can install it as a standalone app and use it offline etc :)
- simmer 7y agoSame issue present when used as standalone.
- theboulevardier 7y agoLooks cool! Any chance of mapping the scales to a guitar fretboard? My favourite way to learn scales is just jamming along to a backing track with the scale on a fretboard in front of me. Like this: http://www.all-guitar-chords.com/guitar_scales.php?scch=E&scchnam=Pentatonic+Minor&get2=Get&t=0&choice=1 http://www.all-guitar-chords.com/guitar_scales.php?scch=E&sc...

- theboulevardier 7y agoThanks, that looks awesome!
- seanitzel 7y agoOfcourse, expect it in a future update!
- tantalor 7y agoBug: In guitar mode I only hear 2 tones for 3-tone chords (expected 3 tones).
- seanitzel 7y agoCheck the octave you are on, there is no C2 note on a guitar... The app has been tested thoroughly :)
- tantalor 7y agoYep was in C2. Not a guitar player, but I think you can tune a guitar to play that note. No amount of testing will protect against incorrect design.
- fenwick67 7y agoNot sure why you're being downvoted, drop-C tuning is a real thing people do (which would bring you down to C2): https://en.m.wikipedia.org/wiki/Drop_C_tuning https://en.m.wikipedia.org/wiki/Drop_C_tuning
- seanitzel 7y agoIt might be a real thing, but it's still not a bug. it's a feature that i will definitely look into adding.
- seanitzel 7y agoYea that is possible, but i dont understand what does the last sentence contribute. None the less, i will try to add those lower notes(which is way more complicated than it sounds for various reasons).
- peapicker 7y agoBass Guitar standard tuning goes to E1...
- jihadjihad 7y agoLooks great! I'll throw this out here as well since I also saw it on HN a while ago, I use it all the time: http://guitardashboard.com/ http://guitardashboard.com/
- holy_city 7y agoThis is really cool! I think the chord naming has some bugs, but it's been awhile since I studied theory. For example all the diminished triads are labeled "min 7-5" which is kind of alien to me (and wrong, there's no 7), shouldn't it be "dim" or "o"? Feature request: viewing the intervals on a keyboard/fretboard, with different colors/numbering for each scale degree.
- jrd259 7y agoIn jazz notation it's common to use minus sign to mean minor or flat. That particular chord (the half-diminished) is written as -7b5
- holy_city 7y agoIt's not half diminished though, since there's no 7? I'm talking about just the diminished triad (min 3rd + min 3rd). It's been years since I read jazz notation (classical background), but I thought that was just written "dim"
- kmill 7y agoThe triadic diminished chords are labeled dim, but the diminished 7th version does indeed seem to be labeled as a half diminished chord. Maybe a circle isn't being rendered for the 7. (It's a bit painful seeing it spelled as C Eb Gb A rather than C Eb Gb Bbb. If you play a string instrument, you might tune an A differently from a Bbb, so it's not just a theoretical difference.) Also, if you're seeing sevenths thrown in, it might be because in jazz chords are more for suggesting a scale than the actual pitches of the harmony. At least, that's how I understand it as a classical musician.
- seanitzel 7y agoI'm working on the spellings to be as accurate as possible :)

- peapicker 7y agoTook me a few tries to find "Hungarian Folk or Byzantine Major Gypsy" scale as I first tried the other aliases: 1. Double Harmonic (main English language theoretical name) [1] 2. Byzantine (finds it, but in my experience is known as "Byzatine scale" and "Major Gypsy" is another scale name -- it is weird to see them glued together. 3. Mayamalavagowla 4. Bhairav Raga 5. Arabic (Hijaz Kar) It would be nice if a given scale had all its known names attached to it.

- slothtrop 7y agoYeah it could use a more accessible categorization for named exotic scales. The amount crammed in there is impressive but depending on what you're looking for, it's too much.
- seanitzel 7y agoI tried to categorize it in a comfortable way, but I'll look into changing it to a more convenient alternative.
- seanitzel 7y agoIt's actually weird because the search option also searches through the aliases of scales, so those aliases might not be present in my database...
- cwilby 7y agoTHANK YOU. I've been passively searching for something like this for years.
- seanitzel 7y agoSo glad to hear!
- seanitzel 7y agoYou can also find it on the play store - https://play.google.com/store/apps/details?id=com.scales.scaleheaven https://play.google.com/store/apps/details?id=com.scales.sca...
- shitgoose 7y agoThe relationship between "Compose" and "Composer" is not clear. You probably can merge it in one screen. Otherwise great app for a total beginner like me! Thanks! And by the way, ditto the dark mode request.
- seanitzel 7y agoGood point, added to to do list :)
- firefwing24 7y agoFrom a User Experience, I would prefer the 4 buttons on the main page to be a button, rather than having the press the text to make it work.
- seanitzel 7y agoTaken, will be changed :)
- dropin685 7y agoNice work! And I have a modest suggestion. I'll illustrate with an example. Let's say I'm browsing scales. I select scale type "classic," and I choose C as the tonic then hit Go. The screen changes, and I see a bunch of scales, including C major (which has no accidentals). Okay, say my theory is rusty (it is, actually!) and I'm thinking about modes. I want to verify that A natural minor also has no accidentals, and likewise D dorian. To do that, it seems I have to back up to the previous screen so I can change the tonic from C to A, then hit Go again. Then I back up to the previous screen so I can change the tonic from A to D, then hit Go again. Can that be streamlined a bit so the tonic can be changed without going back to the previous screen? Something to consider adding to your to-do list! :-)
- seanitzel 7y agoThank you! And added to the to do list :)
- castor_ 7y agoHi! It's very great work indeed. Though I think it would be better, music theory-wise, not to mistake F for E#. For example, when I run the Chord Heaven with C# as the root, it gives C# F G#, instead of C# E# G#. Even if the frequencies of the notes are the same (in equal temperament, obviously), it doesn't convey the same harmonic meaning.
- seanitzel 7y agoI'm looking into ways to improve the pitch spelling algorithm, which is a really complicated thing...
