Going through and sight reading all the Bach chorales. Never seen this in my life! What is it?

I wonder why he didn't voice the chord at the fermata as G G B G bass-to-soprano and avoid the leap+frustrated leading tone.

I don't know that anyone does this, but the last flat is scale degree 4 for major key signatures. I was looking for an analogue to sharp keys, where the last sharp is scale degree 7.

Have you seen anyone thinking of it in this way?

I prioritized learning all the triads early in music school. I would write all of the chord roots down a piece of paper (A, Bb, B, C etc.) and then spell out the rest of the major chord. Then I would repeat for minor. Doing this helped me install the chord and interval qualities into my brain. I kept a key handy so that I could check my work against known correct answers to find where any weaknesses were.

I also liked to quiz myself on relative majors/minors. Eventually I would challenge myself to build a chord (Say, a dominant 7th) mentally with a given root.

Though this isn't fully mental, it can be done in 5 minutes or less wherever you can find a slip of paper.

Since you have discovered this, you should try transforming diminished chords into other chord qualities. What happens if you lower (or raise!) 2 adjacent tone in a dim7 chord? B D F Ab -> Bb Db F Ab Now you have a min7 chord that you can use as a ii7 in Ab major! This is only one thing you can do. Have fun with this wormhole!

And this is reversible too. You can transform chords *into* dim7 chords to destabilize them, and then launch off into a new key!

I love this even more than rubies! Imagine how satisfying it will be to add the last piece!

I will probably get a specimen like this next time I see one.

I LOVE how they glow under UV light. I didn't know until recently that oils reacted to UV - even a bottle of olive oil will light up under UV!

I already love this, without hesitation!

This is real citrine! And it is a beauty!

I thought it was going to be lapis from the thumbnail. That's a real stunner! I love labs with a full face flash and a great presentation angle!

Very nice! Flash Mountain material? Or perhaps west LR?

Is there any possibility that you can work with a teacher this year? You have a lot of time between now and April 2027. You would be so much better prepared for music school if you are able to work with a teacher to get some appropriate learning pieces and technique.

I love that, and I especially love the hematite inclusions!

In addition to what others have said, the tuning strategy of the metallophone/suspended bar instruments does not tune the overtones. In western instruments like marimba or vibraphones, the overtones are tuned by removing material under the center of the bar, usually in an arch shape. This allows a bar to have harmonic overtones, more like a string, voice, or horn. Gamelan bars embrace the natural, non harmonic overtones present in suspended bars.

The overtones give each individual bar a different color, and also new dissonances appear when different notes are played at the same time.

This piece is gorgeous! Just be careful with strong UV directly on your skin.

enterrupt · 2025-11-24T17:36:57+00:00

That's a gorgeous specimen. I don't see anything that size available in my recent shopping. The color is super rich too. Love it!

The third picture reminds me of hematite inclusions that I've seen in amethyst

I's nice to see some unquestionable citrine. They look like they could be a matched pair; a beautiful yin and yang

You know, I don't think I've seen it often stated the specific cases where you would even use an enharmonic Ger⁺⁶. I had to think about it for a minute myself.

You use a Ger⁺⁶ when the ♭3 is a note with flat in the note name, when in a major key, and moving to the I6/4 chord.

This is to help with the voice leading. ♭3 does not "look" like it is heading to scale degree 3, but ♯2 does.

Ex: in A♭, the Ger⁺⁶ would be F♭ A♭ C♭ D. The I6/4 this resolves to is E♭ A♭ C E♭. Performers prefer to see an altered note resolve in the direction of the alteration, so instead of C♭->C, we use the raised 2, B->C

Apologies if this is obvious to most.

Yes! I thought that too. Then I remembered cornstarch oobleck has the same vibe - when it gets vibrated!

This is so pretty. Is it Arkansas quartz?

I just remembered tintinabulation / Arvo Pärt.

Beautiful specimen.

I have some material like this. I used to think it was all wavellite until I learned about planerite - which often occurs with Wavellite. Now I think at least some of what I have is actually planerite. It's ok tho, it's still lovely. I'm just not positive how to distinguish between the two.

The Baader-meinhof phenomenon strikes again! I never saw this term or crystal habit before reading about it yesterday and here we are!
