In the ascending version, notice that the need to raise both the F and the G to F ♯ and G ♯ respectively does not affect the key signature – these sharpened notes are simply ignored. So, “it is so” because Pythagorus said so, and Bach proved it.Interactive feature not available in single page view ( see it in standard view). I like to tell my students that Pythagorus established “rules” hundreds of years before Bach, and then Bach perfected them. Pythagorus was born in 570 BC, and had a huge influence on music and music theory. The Supertonic, Mediant, Submediant and Leading Note (or Subtonic) notes were more dissonant. (In “layman’s terms” – the 1st, 4th, 5th and 8th actually do sound nicer than the 2nd, 3rd, 6th and 7th.)ģ) Pythagorus, the Greek Philosopher and Teacher, basically established the chromatic octave and stated that the intervals of the P1, P4, P5 and P8 were the most pleasing, the most consonant. The ratio of sound for the Perfect Intervals is a simple whole number and therefore has a more “pleasing” sound than the ratio of sound for the 2nd, 3rd, 6th and 7th. In Harmony, using an Augmented Interval (especially the Tritone – the Augmented 4/Diminished 5) is a big “no-no”.Ģ) There is a difference in the sound frequencies of Perfect versus Major/minor Intervals. In music, Perfect intervals are more stable, and do not “change” or vary as much as the Major/minor relationships of the 2nd, 3rd, 6th and 7th. We consider the intervals that use those notes to be “Perfect”. Here are 3 (of many) explanations “in a nut shell”:ġ) The most important notes in a “Key” are the Tonic, followed by the Dominant and then the Subdominant. WOW Kathy! That is a GREAT question! There are actual “scientific reasonings” behind the Perfect Intervals versus the Major/minor Intervals. Join the conversation – Enter your music theory "WHY" questions or comments on Melodic Minor Scales below. It will give me the opportunity to keep on learning…and I love to put on my Sherlock Holmes hat! And then I realized that if I actually knew everything, I would miss out on the adventure of exploring and discovering new theoretic and pedagogic concepts.ĭon’t be afraid or embarrassed to share your “Why” questions below. I used to feel embarrassed and ashamed when I didn’t know the answer immediately to every “Why” question. Have you ever been asked a “Why” question from a student and you didn’t know the answer? Don’t panic – it is okay to say “Good question – and at your next lesson, I will have the answer for you.” Melodic Minor Scales – So why do we have to repeat the top note when writing an ascending and descending Melodic Minor Scale starting on the Submediant or the Leading Note? Because it is not the same note.Because it is the same note ascending and descending, it is not repeated. The bottom note and the top note of this scale is A flat. In all other scales, the starting note is not repeated when writing the descending scale because it is the same note. If your student plays a C natural instead of a C flat, you would correct them. Why? Because they have different pitches. Why are they repeated when they are both C’s? They may use the same letter name, but they are not the same note. They are played on different keys on the piano.
ALL 12 MELODIC MINOR SCALES HOW TO
On in the Advanced Rudiments Workbook, we explain how to write Melodic Minor Scales beginning on the Submediant or Leading Note.Ĭ natural and C flat are different notes. Liam asked me “Why do we have to repeat the Submediant and Leading Note when writing a Melodic Minor Scale when they are the same note?” Because they are NOT the same note. When writing a Major, Harmonic Minor or Melodic Minor Scale ascending and descending, if the bottom note is the SAME NOTE as the top note, it is NOT repeated at the top of the descending scale. When he asked “Why do we repeat the top note in Melodic Minor Scales when it starts on the Submediant or the Leading Note, but not when it starts on the Tonic, Supertonic, Mediant, Subdominant or Dominant?”, I knew the answer! (SCORE!) He loves to ask “Why?” questions as he has a passion for knowledge. My student Liam is preparing for his Advanced Rudiments Theory Exam.
