A ledstrip on a Harp, now I can see the strings at night!
Woohoo .. ( Little harp in the background (autoharp))
Well .. its a pity that the distance of the leds is NOT the same as the strings distance.
I could light up the string to be played, or even cooler …
When using FFT code (Fast Fourier Transform), I could light up the string being played!
I’m probably going to try to implement this at a later time.
While working on a harmony for Irmgard and me in Musescore, i tought it would be nice to have it also in another notation.
Above a Musescore screenshot.
When using below button assignment, we can easily rewrite above into another notation.
Write musescore as MusicML/mxl Music xml.
Install xml2abc from https://wim.vree.org/svgParse/xml2abc.html

We had a delayed Burns night, seems a bit of a habit of our band.
But with Covid, who knows, maybe we are celebrating Burns Night 2020.
I wanted to make Haggis “bitterballen” (Fried balls) but Irmgard has no frying pan. So I made some Haggis sausage rolls.
The others made also a lot of Scottish/Irish themed food. (Too much again) But i don’t have the recipes.
We played some old tunes, and some new. Talking eating and drinking, time flies!
Irmgard and I played a duet on the Harp and some new tunes on the Concertina.
Wellll the recipes:
I wanted to make this one:
https://cookingwithbry.com/haggis-bon-bons-recipe/
Instead I made this:
Mix haggis, sausagemeat and parsley.
I used square “bladerdeeg” for pastry, made a roll out of one square filled with the haggis. (Takes about of 13 sheets).
Brushed on the beaten egg, and put on baking paper.
20 Minutes in a 180 degrees oven.
Cut up each roll in 3-4 parts.
I’ve been playing tin whistles/low whistle for a long time, but I love flutes.
My first try on a Concert metal flute was in a bus with the “Eendracht” to germany. There is a photo but i’ve trashed stuff a long time ago.
A old girlfriend (Noelle) let me try it. Apparently I didn’t do it that badly.
Now 30 odd years later, I picked it up again. But now on the Irish Wooden flute.
We bought it 10+ years, and occasionally I pick it up and try to play some slow airs.
I love the sound of flutes. But I’m bad at lip embouchure.
The Irish Flute makes it even harder, there is no Lip plate.
We have some books, and Coline attended to the Flute lessons in Ireland.
Tunes i’ve been practicing on flute at this time:
(Some are Uilleann/ Low Whistle tunes I already know)
Having a large collection of tunes does not make it easy.
But having trouble myself to get all the octaves correct, I limit myself to certain tunes.
I’ll post some progress / examples at a later date.
Very interesting book and DVD!
Yes, we even tried beatboxing with the flute. (see below)
Some nice flute playing below:
And the best players (according to my opinion)
Sir James Galway
Matt Malloy
Michael McGoldrick
Jethro Tull
Séamus Tansey
Calum Stewart – I play one of his tunes on Uilleann
Paddy Carty
Robert Harvey
Flook stuff
Egyptian flutes are amazing : Lookup Erik the Flutemaker for more exceptional flutes.
Pan flutes from Peru and some asian bamboo flutes are amazing also
I’ve made a overtone flute a while ago, these ones doesn´t have holes.
I’ll post something about those soon.
The last example with overtone reminds me to post my findings about.
(Mongolian) throatsinging, overtone flutes and Altai playing.
(look it up .. amazing, We’ve been to a Hanggai concert)
But i’m drifting away from flutes and the topic in general.
Above McGoldrick with some Fred Morrison tunes i also play.
I stopped www.pipetunesearch.org in 2022. See below link for more info
But i’m getting emails and forum mentions, that people are missing this site ..
So .. it’s back
History about this tune:
https://simonchadwick.net/2020/12/eleanor-plunkett.html
Arranging this tune for a duet. (Imgard and myself)
This is a work in progress
I’m using Musescore for this typesetting
A Nelly an chuil chraobhaigh
Is a shuil ar dhaith an fheir ghlais
Ag eirghe dhon la,
O! nach breag dham so a radh,
’S gur [tu] do shliocht na bhfear eifeacht
O Ardmacha breige,
Fuair sar-chlu o Ghaodhalaidh
Le trean-neart a lamh.O Nelly of the back of the wood
With her eye the color of the green grass
Waking with the day,
O what a lie it is of me to say,
And you with your family from a man of import (?)
O lying Ard Macha,
(Nelly? The man? Ard Macha?) Won great fame from relations
With strength of hand

UPDATE: https://www.henriaanstoot.nl/2024/05/30/c64-mobile-sid-player-using-raspberry/
I’ve got an old Speaker Phat, and a Raspberry Zero
My initial idea was to have the “High Voltage Sid Collection” (Downloaded the 55000 pack)
On a mini device, battery operated and with a little keypad.
On the keypad i can select the Sidtune to play, or pressing
A and a number the Sids from a certain artist.
The display gives you information about the tune being played.
( The display has an I2C hat to convert 8bits to I2C )
See pinout phat above.
I’ve got three choices for I2C connection (green/blue to the Phat)
So I made the first test setup …
Underrun occurred .. So back to the drawingboard.
I probably need a better Audio Hat.
First to try .. Zero fast enough for sidplay2?
Maybe audio over hdmi works??
First I have to replace 4 strings.
Apparently F4 B4 F3 and D1
I’ve replaced strings before so that’s no problem. Starting all over again.
Our Folk Band Harp player wants to due some duets. So lets get playin’
UPDATE: 20230119
Replaced the 4 strings yesterday, not fully tuned yet.
Gave the string some time to rest.
Looking at the harp this morning. G4 was broken .. d*mn
UPDATE: 20230126
Replaced also the G4, all done.
Tuning this kind of Harp. (Salvi Lever harp)
You have to put all levers down, and tune them from lowest note to highest.
The A B and E strings have to be tuned flat!
So by using the levers you can play in all kinds of different keys.
| String | C | D | E | F | G | A | B |
| Tuner | C | D | D#/Eb | F | G | G#/Ab | A#/Bb |
Very nice overview of the keys (harp-school.com)
