Learned scribus last night

learned about DTP (desktop publishing software)

affinity publisher 22$ ios

It has a cool feature called datamerge where you can use spreadsheets to populate designs. Scribus can do mailmerge from csv. being able to patch process multiple things into a cohesive publication is a big deal. the data entry format looks like this.

Here is the link for the python script that adds this functionality
scribus generator

you can print your own shipping labels and make stickers!!

my dim byz

dropbox link

The link is to a pdf I made of spread voiced chords in every key. alternating between a major 6 and a diminished chord to harmonize up the major scale using the b6 as a passing note to create an even octatonic scale. each diminished chord can resolve to 4 different keys. page 4 is on half whole diminished scales on ukulele and then I included a few other scales for fun

every dim7 substitution

mapped it all out as mermaid then touched it up in autodesk sketchup
bc it was super short and wide.
previewed it with mermaid js
screenshot with flameshot
added mermaid js and markdown support to my blog to try
to do it all with mermaid but im not going to keep it
I like using html now and its not worth loading the
highlight js cdn twice.
ai upscaled it in ibispaint because it was pixelly.

Best Native Teleprompter on apple

ios and on mac you can use the pages app. It has a scroll function. I don't trust the free apps the data harvesting creeps me out. many of the paid ones you can't even own they are like a 60$ yearly subscription. Even after you buy them you still need to by a two way mirrored glass camera attachment. If its not going to be good even after spending 60$ Id rather just memorize it. If your eyes arent looking at the camera directly theres no point. Might be useful for some makeshift karaoke

Notice how the third isn't voiced in the right hand on the 5th degree but it is on the 1st, 3rd and 6th. The third is in the left hand on the 3rd degree as the bottom note, then on the 5th degree the third is the top note in the left hand. It's absent from the left hand on the 6th degree while the RH takes it.

Its cool how the third shuffles back and forth between hands. On the 3rd degree the pinkies get joint custody on that day.

the grand staff and hz values

my mnemonic for visually finding notes that align with the logarithmic markers on tb spectrogram was approximately

glorious g1 50ish hz
green g2 100ish hz
grapes g3 200ish hz
beat b4 500ish hz
big b5 1k
bells b6 2k
ebony eb8 5k
ebeneezer eb9 10k

Maybe instead for the limited range I'll make it "green grass blue birds. for approx 100hz, 200hz, 500hz, 1khz"

the lines on sunvox's spectrogram seem to visually align with c notes and powers of 2.

heres my annotated graphic of the grand staff with some significant pitch landmarks to help make sense of the bigger picture as to where the notes all fit in. Notice how glorious ebony ebeneezer bells doesn't fit because it extends beyond the ledger lines. (no g1, b6, eb8, eb9)

how to tune a piano to et using a single reference pitch

This could all be hogwash but I thought it was interesting.

the first few intervals are downa 4th till you get to c4 which is a tritone away. Down again a 4th to g, up a fifth then d down to f, d is the maj 6 of f or f is the minor third in d. After that f3 to f4 is octaves.

Step	Note	Direction	Beat Rate (approx.)
1	A4	—	—
2	E4	Below	0.9 bps
3	B3	Below	6–7 bps
4	F#3	Below	3–4 bps
5	C4	Above	5–6 bps
6	G3	Below	2–3 bps
7	D4	Above	1–2 bps
8	F3	Below	4–5 bps
9	F4	Above	0 (octave)

This gives you a base for equal temperament from f3 to f4 which you can expand outwards tuning to octaves and checking against 12ths (octave and a fifth) to get the rest of the notes.

how off is et from ji

Most off:

Minor seventh (7:4): +31 cents
Major third (5:4): +13.7 cents
Minor third (6:5): −15.6 cents
Major sixth (5:3): +15.6 cents

Closest to just:

Perfect fifth/fourth: 1.96 cents off
Octave: perfectly in tune

Frankie Lymon "Little Bitty Pretty One" Vocal Exercise

dropbox link to the audio file

Original was in Bb
I pitched it down to start on G to give you a bit of room to warm up into the Bb.
I automated a formant shift so as it pitches up it doesn't sound as chipmunked.
This Exercise moves through all 12 keys using the mm sound

The MM Sound

Gently Engages the Vocal Folds
The "mm" sound, especially when done lightly (like humming), encourages your vocal folds to come together without too much pressure. It helps you get your voice going without strain.
Resonance and Placement
It brings the vibration forward, often felt in your lips, nose, or face (aka "mask"). This helps with resonance, which makes your voice sound fuller and carry better.
Breath Connection
Doing "mm" helps you manage airflow and breath support. You’re not pushing too hard, so it keeps everything in check — breath, tone, and tension.
Lip and Facial Relaxation
It warms up facial muscles and gets your articulators (lips, cheeks, etc.) moving in a relaxed, focused way — which is great before diving into more intense singing or speaking.
Easy Onsets
You can explore clean onsets (how your voice starts) without attacking the note harshly. It's like easing into singing instead of jumping in cold.

Fun Fact : 251hz Is Very Close To Middle C

c4 = 261.63hz
b3 = 246.94hz

its b3 27.94% sharp
251 hz is b3 + 28 cents

Determining if 251 Hz is a Sharp B3

The Problem

Determine whether 251 Hz represents a sharp B3 note by calculating its position between the standard frequencies of B3 (246.94 Hz) and C4 (261.63 Hz).

Step-by-Step Calculation

1. Identify the Reference Frequencies

B3 = 246.94 Hz
C4 = 261.63 Hz

2. Calculate the Distance Between Notes

The full semitone distance between B3 and C4:

Semitone Range = 261.63 Hz - 246.94 Hz = 14.69 Hz

3. Calculate the Distance From B3 to Our Target

Target Distance = 251 Hz - 246.94 Hz = 4.06 Hz

4. Calculate the Percentage Position

Position Percentage = (Target Distance ÷ Semitone Range) × 100%
Position Percentage = (4.06 Hz ÷ 14.69 Hz) × 100% = 27.64%

5. Convert to Cents

In musical terms, one semitone equals 100 cents. To convert our percentage to cents:

Cents from B3 = Position Percentage × 100 cents
Cents from B3 = 27.64% × 100 cents = 27.64 cents

Conclusion

251 Hz is a B3 note that is approximately 27.64 cents sharp. Since this is less than 50 cents (which would be halfway to C4), we can properly describe it as a "slightly sharp B3" rather than a flat C4.

Formula Summary

To find where a frequency falls between two reference notes:

Calculate the semitone range: HigherFrequency - LowerFrequency
Calculate the target distance: TargetFrequency - LowerFrequency
Calculate the position percentage: (TargetDistance ÷ SemitoneRange) × 100%
Convert to cents: PositionPercentage × 100 cents

Tuning an Instrument to Room Resonance

Goal:
Make your instrument lock in with the natural resonance frequencies of the room, so it sounds fuller, louder, and more "alive."

1. Understand Room Resonance

Every room has natural frequencies it favors — like how a wine glass vibrates at a particular pitch.
These resonant frequencies depend on:

Room dimensions (length, width, height)
Surfaces (walls, floor, ceiling material)

At certain frequencies, the sound waves bounce perfectly and amplify themselves.
Those pitches are where your instrument will sound best or loudest without extra effort.

2. Find the Room Resonant Frequencies

You have a few ways:

Quick and Ears-Only Method

Stand in the middle of the room.
Hum a steady low pitch.
Slowly glide your voice up (like a slow siren).
You'll notice some notes "bloom" — they get louder or feel like the room "catches" them.

When you hit one, hold it. Walk around.
If it stays loud in multiple spots, that's a room resonance.

Write these down (even roughly):
Example: "Somewhere around a low A" or "near middle C."

Technical Method (Optional)

Use a tone generator app (many free ones exist) and sweep from 20 Hz to 500 Hz slowly.

When the tone gets super loud without raising the volume, that's a resonance peak.

3. Tune Your Instrument

Once you know the resonant frequencies:

Match a string or note on your instrument to a nearby room resonance.
You don’t have to match exactly — being close can still boost the sound.
Tiny detunings (a few cents sharp or flat) can help maximize resonance.

Example:
If your room has a big resonance around 110 Hz (A2),
you might slightly adjust your guitar’s tuning so the open A string aligns even better.

4. Play and Adjust

Strum or bow or pluck your instrument near the center of the room.
Listen for notes that seem to "hang" or get louder with less effort.
Slightly tweak tuning until certain notes or chords ring out.

5. Other Tips

Height matters: Some notes resonate better higher up (standing) or lower down (sitting).
Corners boost bass: Low frequencies are stronger in corners. Try playing there.
Move around: Find "sweet spots" where both you and the room are happy.
Use harmonics: On strings, lightly touch at 12th fret, 7th, 5th — natural harmonics often catch resonances strongly.

Why Do This?

Bigger, richer sound.
Easier to project without forcing.
Can make a cheap instrument sound surprisingly powerful.

Bonus: Use It Musically

Tuning your drone notes (if you’re using one) to a room resonance makes the whole room feel like it’s vibrating with your music.
Great for solo performance, ambient setups, and recording.

using this knowledge you can pick out frequencies on an eq or tune up just by eyeballing what lines up with your scope
