Middeleeuws orgel / Mittelalterliche Orgel / Medieval organ 

These were the original organs. Dating back to the BC era Greek hydraulis.

Get out the red pen!

My goodness, how old are you?!

@@aerodynamikapieroga I'm only 81 in this lifetime, but I strongly believe I had a life in that era as well. I feel a strong connection with music of that time.... Thanks for your reply.

​@highphlyer Same. It's surreal. It's almost as if I feel like I belonged in that time.

portatief they have to be synchronised. Half height at the same time rising and falling

If I have understood it well , this is not medieval music but improvisation ( so, nowadays ) in medieval modes.

That something has an effect is in no way evidence that this effect was understood when the thing was invented. Understanding of the brain and how it works is historically fairly recent.

+Isak Zachariasen I think what he meant is that medieval composers had a better idea about how music sounds to the brain. They composed based on perception rather than worrying pedantically about whether it it follows some arbitrary rules like most western classical music composers have done since the 1500s. Ever since the renaissance music theorists have pushed their views as some sort of law that must be followed, and anything in the past was considered inferior or primitive (like writing music based on modes rather than diatonic scales.) But thankfully due to the internet we have access to so much medieval and world music that it makes those theorists look stupid.

Speaking as a historian, I'm fully aware of this. And I stand by my original statement that such notions are a historical anachronism. I'm not saying classical composers were stupid. There are mountains of evidence to the contrary. But ideas of ancient wisdom lost to the aeons waiting to be discovered are, in my experience, usually unfounded.

I think Dillon, the OP, expresses/translate in his current terms what in old days was felt (no science explanations needed for feelings). Just replace the term Brain for Person. ("How sound affects people"). So, i see no anachronism here but the opposite. (Re-afirmation of current science dogma) Do we need equipment to confirm we feel the alpha waves?

+TenorCantusFirmus . Why not? Very much is not traceable about the 14th c. organs.The only way is to make a reconstruction, like Winold van der Putten does: www.orgelmakerij.nl/

+Jankees Dus If it would have been Machaut's organ, it would be interesting to record the Messe "de Nostre Dame" with such an instrument doubling canti firmi in the movements based on them (Kÿrie, Sanctus, Agnus Dei and Ite, Missa Est) or the entire texture in appropriate sections of those "freely" composed (Gloria and Credo). After all, as only instruments allowed in Church, we have traces of organ in European Churches since the whole High Middle-Ages (that is, 1000 ca. onwards), as such they likely have been used, at least in some occasions, in combinations with Choirs also in Liturgies all this period long.

1. Tuning is pythagorean after Arnout van Zwolle (ca. 1440); pure fifths, one devil (h-fis) and a-cis, h-dis, d-fis, e-gis are pure thirds. 2. It sounds like that because a fifth is added to the dorian

@@jankeesdus3204 Very beautiful piece, sounds very harmonious! This comes to show that modal music have potential too, its not just a relic of the past.

Winold van der Putten (NL) made it for the late David Rumsey (CH). The instrument is now in Linz, Austria, with Brett Leighton. Some remarks and details: www.davidrumsey.ch/amsterdam%20program.htm

I made it. Winold van der Putten.

Yes it is a big positive organ. Transporting is done a lot with this instrument.

+jukingeo Strictly speaking, this is a "Postive" a "Portative" organ is one that is carried. "Positio" - Latin -a placing (or to put in place, from "ponare") and "Portatio" - Latin -a carrying or conveying. (related to "porta" which literally means "a gate")

+Martin Hartley I am still coming to grips with all the terminology surrounding pipe organs. When I first heard the term Positiv, I thought...well is there a Negativ? LOL. Then I got to thinking positiv and portative were the same. Then another 'p' word entered the mix, pentatonic. So I have a tendencies to get my 'p's of the pipes all mixed up.

The bellows on this are hearth bellows like those used by the blacksmith as they are unreinforced & are billowing like a balloon.Proper organ bellows are of rigid construction with wooden staves or card to make the leatherwork rigid so it does not blow outwards.

Improvisation in d.

The bellows are domestic hearth bellows as the leather is billowing like an overblown balloon as organ bellows are rectangular and the leather is made rigid with staves of wood to stop it billowing as these bellows could burst at any moment.Did they use hearth bellows for organs in the middle ages?

Christian Jiang actually it's more complicated. The more "medieval" sounding version of Greensleeves was written in the late 19th Century by Ralph Vaughan Williams with the then modern world's conception of ancient music. The original was written during the Renaissance, rather than medieval, and always had the more tonal "alterations" of the standard version.

@@KennyReganThat’s super interesting! True, a lot of the “medieval” music that we hear nowadays is probably closer to what we think medieval music would sound like, than to what it actually sounds like. Where can I read more about this?

@@ChristianJiang The RU-vid channel Early Music Sources is an excellent resource for exploring late medieval and Renaissance music, and they also link further reading material on their videos!

@ChristianJiang their video on musica ficta talks about this very topic, the historical practice of performers adding sharps or flats to the scale depending on the musical context ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-6VF6YkCNRyE.htmlsi=K_E4TGPM-GpVPp6_
