I need help with music theory I feel ashamed

[Guest]

So basically I don’t know the names of the intervals obviously I know what a whole note and a half and all that but I don’t know where major 2nd minor and so on goes doss anyone know how to help with leering the name of the intervals I need some help please. Also I feel like I’m stuck, I need to learn this so I can learn more advanced music theory because that’s what I want to do anyways thanks in advance

I’m quite rusty on these subjects myself. But if I’m not mistake “major second” and so on, will relate to whatever Key you’re working in.
For example, in the key of C there are no sharps and flats. And so the interval of major 2nd would be C to D. Whereas if we were looking for a minor 2nd, it would be C to Db I believe.
I hope I’ve helped! If I’m wrong, someone please correct me!!!

And so a major 3rd in the key of C would be C to E. Because if we thing about the C major scale, the E would be the 3rd tone in the scale. Whereas Eb would be the minor 3rd.

Make sure you understand how your major scale works at least first before you take on intervals. This can get involved so bear with me. I’ll try to break it down.
First you need to know that intervals are distiguished by two elements. They are:
1. Quality (Perfect, Major, minor, Augmented, Diminished)
2. Number (Unison -the same note-, 2nd, 3rd, 4th, 5th, etc)
*NOTE* I believe that the Unison, 5th, 8th (octave) intervals area always ‘Perfect’ intervals. The 4th can be either perfect or Augmented 4th (Aug4th) or it can also be written like Diminished 5th (dim5th)
Combine them together and you get things like Minor 3rd, or Major 4th.
HOW TO FIND AN INTERVAL’S NUMBER
First you want to find out the distance between two notes (this is where a keyboard comes in handy).
*Example* the note C to F. This contains the notes C, D, E, and F. So already you know that the NUMBER of your interval is going to be a 4th (four notes C, D, E, F)
HOW TO FIND THE QUALITY (Major, minor, so on and so forth)
First understand what a SEMITONE is. A SEMITONE is a ‘half-step’ between two notes. Such as C to C#. Or B to C. From C to C# is ONE semitone (half step). You need to simply memorize the amount of semitones for each interval. They are as follows…
(st = semitone)
2 st = major 2nd
4 st = major 3rd
5 st = perfect 4th
7 st = perfect 5th
9 st = major 6th
11 st = major 7th
12 st = (perfect) octave
So if we have the key of C major, where the notes are C D E F G A B C, and we have an interval of C and E. There are 4 semitones from C to E. So if we memorize our little chart above, 4 semitones equals a Major 3rd.
Now how do we find a MINOR interval? Such as a MINOR 3rd? You simply make it a minor by taking ONE semitone away. So if we had C to E is a Major 4th because it has 4 SEMITONES, you simply take one away and end up with 3 semitones, or a MINOR 3rd.
Let’s exercise this…
C to E is a Major 3rd. But if we were to drop E down to D#, we’d lose ONE semitone, and then it will become a MINOR 3rd.
I hope this helps! Make sure you know how your major scales work and the notes in them!

*NOTHING* to be ashamed of.

This part needs to be edited as my phone changed it.
Now how do we find a MINOR interval? Such as a MINOR 3rd? You simply make it a minor by taking ONE semitone away. So if we had C to E is a ****Major 3RD**** because it has 4 SEMITONES, you simply take one away and end up with 3 semitones, or a MINOR 3rd.

Let’s start with the major intervals (music theory is generally looked upon from the major key the I chord is always major) now take any natural major scale(first mode) and look upon the code of the scale which is 1 2 3 4 5 6 7 that basically means that the first note is the root, 2nd is the major 2nd, 3rd is major third etc. Now looking upon the minor intervals you can basically get those by flattening all the major intervals by a semitone so you get 1 b2 b3 4 5 b6 b7 are minor intervals (the fifth is a perfect fifth which basically means it’s the same for minor and major and the same for the 4) Hope this helps!
