![]() And so it goes with all modes and scales.īecause today we tend to think of the C Major and A Minor Scales as the basis for our tonal system, everything else we refer to as "modes", but it's by no means so clear-cut, and in truth it's simpler than one might think.The goal of Half-Life 2 : MMod is to enhance and expand gunplay, combat mechanics and the immersion factor by giving the Player more options and combat opportunities as well as refine how the Player handles his arsenal. In fact, if we decide that A Aeolian is the parent scale, C Ionian would then be considered the third mode of A Minor. But note that C major also has a modal name: Ionian. So using the example of C Ionian - which we call the C Major Scale, the 6th mode of that scale - a scale that starts on the 6th degree of the parent scale, (whose key signature has no sharps and no flats) in this case A - becomes the Aeolian mode, commonly known as the A Minor Scale. Mode is a relative term: when you decide, for whatever reason, to make one particular note your root, that pattern is called the scale, and becomes a 'parent scale', as it were, to its other modes: Building a scale with the same key signature but using a different root than the 'parent' root becomes a mode: A different fashion/manner of playing the parent scale. There is no absolute difference between a mode and a scale: Every scale has a given key signature and one can play any ordered collection of 7 notes using that key signature - start on any note in the chromatic octave (which has no accidentals) and play a conventional 7 note scale, following the key signature - you now have a what's called a scale or mode. Mode in the musical sense means a 'manner' or 'fashion' of playing a scale. The term mode is often the subject of confusion, but it's really quite Of the seven, Ionian is the same as Major Scale, Aeolean is the same as Minor Scale The mode is determined on which tone in the pattern the melody or piece is focusing on (the tonic). The key signature in this case should have two sharps in it.Įach Key signature contains the notes for all seven natural modes. Modal music will be described by its actual key, so you will hear "E Dorian", meaning the tonic is E and the scale pattern is Dorian. If the key signature shows C, but the Tonic is G and F#s are added, then the diatonic pattern you are playing is G major. You would not say that you are playing C Lydian mode in the key of C Major (except to describe how the piece was written out in the transcription). To answer your example, if your key signature is the same as C major and you see the Fs turned into F#s, if the tonic is C then you would say you are in the key of C Lydian, even if the key signature indicates otherwise. I believe this is usually because the method book hasn't advanced to explaining key signatures yet. In some method and instructional books, you will also see the key of C major, but the piece is actually G major, and the F#s are added in as accidentals. The same is true for Mixolydian pieces, (g-a-bc-d-ef-g) where the F# is in the key signature indicating G Major, but all the #s are removed in the piece with accidentals. Musicians that learn Major-centric theory are expecting only one of two tonics in a key signature, the Major tonic and the Minor tonic.įor example, you will see a Dorian tune (d-ef-g-a-bc-d) written in D minor key (one flat, the Bb in the key signature), and every single Bb in the piece will have a natural sign in front of it. I believe this is done so as not to confuse musicians that have learned only Major/Minor as key signatures and scale. It often happens that a modal music's key signature is written in a parallel major/minor key, and adjusted into the modal pattern by adding or removing accidentals. The "key" in many cases can be determined by the tonic note of the piece, and the tonic's position in the diatonic pattern.
