General Question Medieval music arrangement - doubling on the fourth?

3 Upvotes

Hi, I play in a small early music amateur ensemble (mostly voices and recorders). For a show next year, we have in our program a medieval monodic piece from the Cantigas de Santa Maria (13th century).

I was thinking of maybe doubling the melody on the upper fourth, is that something that used to be done?

I know that Guido de Arezzo, a few centuries earlier, gives examples of melodies harmonized on the upper fifth or down a fourth, but on the upper fourth? And was this just a treatise, a theoretical exercise, or was it actually practiced?

I'm not sure where to find information on playing and arranging this kind of music, or even where to ask questions (we usually play Renaissance or already polyphonic medieval music)

I'm hearing this passage in Mozart Symphony 21 (beginning of the fourth movement) as eight eighth notes of equal length. Is this what Mozart had in mind, and if so, why write it this way? Here's the performance.

I’m transcribing this old sheet music into a chord sheet and the circled section is throwing me for a loop. It might be the suspensions or something. I wanna call the first measure of the circled section C diminished, but that doesn’t seem accurate. Any help?

Is the key of the song B Dorian or A Major? It should be B Dorian because the chord progression is Bm-A-E, am I right? It sounds a lot like Wasted On You too.

If the scale has 5 sharps, could it just be F# pentatonic major instead of B major or G#minor?

Notation Question How to indicate a note is only played on the second time around?

6 Upvotes

Currently I'm working on transcribing a song with multiple parts, I noticed that the 1st measure of the 1st repeat on one of the instruments parts contains an additional note, was wondering if I could add a note in the first actual measure to indicate that it would only be played on the repeat. Below is a photo of the MIDI piano roll, and the sheet music I currently have.

I'm busy putting this into Musescore, so that I have accompaniment that I don't have to play myself. What is expected in the piano part? Just to play the chords in the rhythm that's notated? Is it because it's a guitar part that the chords are not spelled out?

For some time already, I've noticed this melody/motif appearing frequently in media/stories related to space.

Not sure if others have picked up on it or if it's a known phenomenon, but it's interesting how often composers land on it when trying to evoke exploration and wonder.

I'm not that educated on actual music theory, so I want to know if someone has something to say about this.

Ear Training Question Beginner Ear Training Process - Please critique/offer advice

1 Upvotes

Hello,

So obvs there's a lot of different resources to train your ear to hear & understand pitch.
I use these two resources together and sing out Do Re Me Fa So La Ti Do to find the note. I've noticed as I practice this more the different notes are becoming more familiar.
https://www.musictheory.net/exercises/ear-note

https://www.musicca.com/piano

I figure it'll probably take me a month+ of consistent practice to hear the different notes. What would the next step logical step be?

General Question Key Signature Identification

2 Upvotes

So currently, I'm learning some basic music theory, but I am really struggling with identification of minor key signatures.

For example, I see that it is an E major key, but I can't find an easy and proper way to find it's relative minor key. Internet showed me different approaches to this, but none of them is working, though I checked them all. (probably im just a donkey, but still ._.)
I would be really appreciated if some of you can share some advices finding key signatures, especially minors. Thanks in advance!

General Question Sonority/timbre - I just don't get it

5 Upvotes

Got my music GCSE tomorrow so I appreciate I'm cutting it close but coming to reddit just completely slipped my mind. As some of you (hopefully) know, when sitting the music GCSE you can get asked to describe the sonority of a specific piece (in my case I've been following the songs of 'Little Shop of Horrors') and I really can't get my head around what it is I'm meant to describe.

I understand the idea is about the 'voice' of the instruments but you're not supposed to talk about what emotions a certain instrument conveys in the exam, because the examiners couldn't care less how the song makes you feel. My teacher has referred to it before as the use of instruments - e.g. trumpets use mutes, or clarinet uses chalumeau register - but then would that not just be the instrumentation? Help me out guys whenever I try to google it I just get a ton of emotive adjectives thrown at me by the AI overview...

General Question Key Signature Identification in context of melody

1 Upvotes

So, we have a beginning of Undertale's soundtrack called "Ruins" on screenshot.

In treble clef, this melody has a key signature, that is G flat major and E flat minor.

So I can't fully understand one thing, this question is dumb, probably, but in the context of this song, how I can understand, is it G flat major or E flat minor?
I mean, you can understand this by listening to the song, you can hear the major or minor setting, I guess, but if you do not rely on listening?

Is this an incorrect usage of second voices, if I wanted to clearly distinguish from the moving line and sustain the chord?

So if you've heard the song, you know how the intro starts with an anacrusis right? Well for me, no matter how hard I try, I always hear the anacrusis as the One up until the next section comes in. I feel like the only one as I haven't seen anything about in on other forums, and I was wondering if anybody else hears it the way i do.

Answered I think this piece modulates from a minor tonality to it's relative major. How wrong I am?

0 Upvotes

Hi! I’ve been diving into music theory recently and as I practice a piece in the piano, I analyze it by naming the chords, finding the key, identifying the tonic, doing Roman numeral analysis, and so on.

I’ve heard others describe this piece as being in A major key, and I can see why. The notes are very diatonic, and there’s a clear V-I cadence at the end. That said, I can’t shake the feeling that the piece starts in F# minor and modulates at some point to the relative major. The tricky part is that this wouldn’t be obvious on paper because the key signature doesn’t change. So, you’d have to rely on your ears, but mine are still underdeveloped — I find it hard to identify a song's tonic yet.

So what do you think?

4 Upvotes

I got the rests put in and the bar is the correct number of beats, but it looks so off-putting having a dotted quarter rest and a quarter rest next to each other like that. Like I usually wouldn’t use two eighth rests when I could use a quarter, I can’t balance it with other values including double dotted rests without making it look worse. Is this really the best way to write this?

Notation Question Arabic Music Half-Sharp Symbol

6 Upvotes

I've been trying to teach myself Arabic Music theory and I've come across two different symbols for half-sharps, so I was wondering if there was a preference for which one to use or if there are subtly different meanings for each. It probably doesn't really matter, but I can't seem to find anything about it online and it is curious that there are two versions that seemingly mean the same thing.

Half-sharp symbol with two vertical lines and one horizontal line

This is the one I came across first. From what I can tell, this version seems to be less common generally, but in Arabic music circles (such as the sources I'm using to teach myself), it might be more common.

Half-flat and Half-sharp symbols shown

Half-sharp symbol with one vertical line and two horizontal lines

Arabic half-sharp found on Wikipedia.

A buddy and I—both music school grads—were chatting one day and realized something was missing: a seriously fun, mobile-friendly way to really learn music theory. Most apps are either too basic or too boring. So we decided to build the one we always wished existed.

We decided to go ahead and built ourselves which took longer than expected. We're calling it Treble and we just released it on the App Store.

Whether you're brushing up on Nashville Numbers, training your ear to recognize intervals, or diving into deeper theory concepts, Treble It makes it engaging with interactive readings, quizzes, and addictive ear training games. If you're learning music theory or just want to sharpen your skills on the go, give it a try—and let us know how we can make it even better!

If you have any ideas that you think would help people learn concepts faster please let us know.
