What Are Scales?
A surprising number of piano students are not able to answer this question in a meaningful way, nor make the connection between scales and the music that they play or listen to. Perhaps this is where the dread of practicing scales come from; after all, given time, anyone who does not have a clear idea of the purpose of doing something, will most certainly come to see it as a do-for-the-sake-of-doing-it chore. It would then be prudent to first think about the question: what are scales?
There's more than one way to answer this question, but let's approach this from a utilitarian standpoint. Imagine for a moment, that you were a composer of music who's brand new to the craft. Now, with all the 12 (chromatic) notes of music available to you to compose a piece of music, it can seem a little overwhelming with the amount of possibilities that having 12 notes presents. What do we do then?
Imagine, then, that if someone came along and told you, "Hey, if you made music only using C, D, Eb, G, it gives you a dark sound; it's most useful for composing music that sounds sad or anguished; or possibly something cool and hip given the right rhythms".
Now, that would've been useful because it narrowed down your choices from 12 notes to 4 specific notes, and there was also a particular mood associated with this set of 4 notes. You begin to wonder to yourself, "Are there more of these sets of notes? Perhaps one with brighter sounds and colors that I can use for a happier composition. Or perhaps one with a blues-ey sound to it so I can compose something cool with it?"
Ladies and gentleman, this is exactly what scales are: they are pools of notes that composers draw upon, to craft music compositions. Whether they contain 4 notes, 5 notes, 6 notes, or more, each scales has its own unique character and sound. Yes, for those who have been brought up on a musical diet of only 7-note scales such as major and minor scales, it may be hard to wrap one's head around the idea that there are such things as 4 or 5-note scales, or the fact that there's an entire world of scales beyond the major scale and 3 minor scales. But your journey into scales is just beginning at this point.
Why You Should Practice Scales
Now that we have established what scales are, it shouldn't be hard, then, to appreciate some very direct benefits of being familiar with your scales. Given that scales are the basic material that composers use to write music, mastering your scales should, in theory, puts you in a better position to quickly make sense of any new musical material that you are attempting to learn.
For example, mastering your scales translates to strengthening your key awareness - knowing what notes belong in a key, and what notes do not belong. This means that when learning a new piece of music from written notation, there would not be a need to continuously check every new note read against the key signature to see if the note needs to be sharpened or flattened - a poor habit of a good number of piano students. With a strong key awareness, you would simply know which ones need to be sharpened and flattened, unless you see an accidental that states otherwise.
Mastering your scales should also, in theory, build better intuition towards determining fingering choices for any given situation. This is especially so if it the passage that you are trying to learn uses scalar patterns or scale fragments. In these cases, having mastered your scales, your fingers should intuitively default to the fingering that has been practiced in your scales.
If you were a pop piano accompaniments with an interest in playing chords, mastering your scales translates into having a strong key awareness, and this directly pertains to the ability to transpose songs into different keys quickly, which is a useful skill for playing with different lead players or singers with differing keys. But even before transposition, mastering your scales also means that you will be better positioned to quickly construct chords that are unfamiliar to you.
For a newer student of the piano, practicing scales also provides an opportunity to strengthen the fingers and develop the most basic coordination skills between the hands.
Practicing your scales can also take on the role of shorter term goals or objectives in your practice routine. Think of practicing scales as practicing tiny pieces; practicing your scales provides the perfect bite-sized opportunity to develop mindfulness - the building one's mental muscle to pre-emptively think, hear and visualize ahead of time.
How To Practice Scales
You might have noticed that I used the term 'in theory' multiple times when discussing the benefits of practicing scales. Yes, this was deliberate. After all, for every benefit that one could potentially derive from practicing scales, there is always a way to miss the learning objective and the accompanying benefits when practicing scales. The question is then, how do you know if you're practicing them right? Here's a few pointers
Pointer #1: Always Practice With The Correct Fingerings
Practicing with correct fingerings is key to building speed and consistency. When practicing scales, it doesn't count as a correct repetition if the fingering is incorrect.
Pointer #2: Practice Only Begins After You Get It Right
Practice only starts proper after getting several correct repetitions; if you are in the habit of approaching practice with a 'try-until-you-get-it' manner, and conclude your practice the moment you get one or two correct repetitions, you will not benefit from such practice.
Pointer #3: Practice With A Steady Pulse
When practicing your scales, play them with a steady pulse. A metronome will serve you well to this end.
Pointer #4: Adjust The Unit Of Repetition
Having the correct fingerings, a steady pulse, and consistency is a non-negotiable. However, if you are having trouble holding these three things together, don't just take a 'try it again' or 'try until you get it' approach. Adjust the unit of repetition to something smaller in order to balance these three things. Here's what I mean, if you can't play the whole scale correctly in a consistent manner, adjust the 'unit of repetition' (the thing that you repeat during your practice) from the entire scale to only playing a small number of notes from the scale, for example, the first 4 notes of the scale. Practice just the first 4 notes until you can balance all three aspects (fingering, steady pulse, consistency) every single time you play them. Only then do you add more notes to the unit of repetition, and it can be just one single note (eg practicing the first 5 notes, after you've mastered the first 4 notes). Be patient with your practice!
Pointer #5: Teach It Back. Verbally Only!
After having practiced a scale, ask yourself the following question: if you were to placed in the piano teacher's seat and had to teach back the scale to someone else the same scale verbally, would you be able to do it? Here's the catch: while you're doing this, it has to be purely verbally; you're not to place your hands on the keys or gesture in the air how you would play the scale, lest this exercise loses its purpose. The idea here is to strengthen your mindfulness of what you intend to play and the ability to visualize. Too many students rely on momentum to practice without developing any meaningful mindfulness of what they are playing and the actions they are taking at the piano; this is a classic example of the expression, 'the tail (hands) wagging the dog (mind)'. This leads to lack of consistency and a lesser ability to make connections between one piece of knowledge to another. A big part of the act of playing the piano begins from the mind, and as such, when doing this 'teach back' exercise, it should be done only verbally; the idea is to remove the physical component of practice and isolate just the mental aspect of practice.
Pointer #6: Switching Between Scales Without False Starts
After having practiced a couple scales, ask yourself the following question: are you able to switch back and forth between the scales that your know without 'false starts'? For example, if you have already practiced the scales of C and G major, try practice switching back and forth between them - one repetition of C, followed by one repetition of G, and back to C, and then G again, and so on. When doing this exercise, are you able to switch between keys without making any mistakes? Or do you find yourself constantly playing a few incorrect repetitions first before getting it right during the key changes? For example, you might find yourself playing the first couple of notes of the scale, and then realizing you made some kind of mistake, before starting from the beginning of the scale again - this is what I refer to as 'false starts'. These 'false starts' are the signs and symptoms of a lack of mindfulness as mentioned in the earlier point. If you find yourself habitually having 'false starts' when switching between the scales you have practiced, then it is an indication that you have to rework your scales with greater mindfulness.
Pointer #7: Knowing Your Scale Degrees At The Snap Of A Finger
For any number of scales that you may have learnt, ask yourself the following question: how quickly are you able to visualize your scales to answer questions like, 'What is 6th note of a F# harmonic minor scale?'. If answering a question like this invokes a need to play out the scale or even pretend to play out the scale without a keyboard, it is an indication that there can still be more to be done to internalize the scale, and that the scale is not 'mastered'.
Mindfulness Is Key
You might have noticed by now, that a big recurring theme of the last three pointers is mindfulness. Indeed, mindfulness is one of the biggest aspects of mastery, but it can be a little elusive of definition, hence the last three pointers has been given as a litmus test of sorts for mindfulness; it is not definitive, but gives a rough gauge of whether more can be done to master your scales.
All The Basic Scales You Need To Know
Below is a list of all the scales you need to know, and for simplicity, they are written in the key of C.
The major scale is the most basic of scales. It is constructed using the following intervallic structure
Knowing your major scales can be very useful as many teaching resources would define other scales, chords and harmonic techniques and/or analysis terms in relation to the major scale, using a numbering system (sometimes referred to as 'scale formulas'**).
For example, a textbook with a topic on scales might say, "The Minor Blues Scale is constructed with the following scale formula: 1, b3, 4, #4, 5, b7"
In this case, 'b3' would refer to a regular 3rd note in a major scale, but flattened (lowered by half a step). Hence, if you were trying to figure out what a 'b3' is in a C minor blues scale:
3 = 3rd note in C major scale = E
hence, b3 = Eb
However, had you not known your major scales, you would not be able to figure out what a regular 3rd note is, let alone a flattened 3rd note. Hence, it would serve you well to know your major scales.
** The term 'scale formulas' are used loosely to mean different things by different people. It would be good to know the differences. For some, 'scale formulas' refer to numeric descriptions of scales with reference to the major scale. For example, someone might say, "the scale formula for natural minor scale is 1, 2, b3, 4, 5, b6, b7". For others, 'scale formulas' refer to intervallic structures. For example, someone might say, "the scale formula for harmonic minor is Tone-Semitone-Tone-Tone-Semitone-Tone-Tone"
Harmonic Minor Scale
The harmonic minor scale is characterized by a raised 7th note. If described as a numeric scale formula, it would be as follows:
1, 2, b3, 4, 5, b6, 7
Melodic Minor Scale
The melodic minor scale has two forms: the ascending form and the descending form. For the ascending form (see scale above), the 6th and 7th scale degrees are raised. The numeric scale formula is as follows:
1, 2, b3, 4, 5, 6, 7
For the descending form (see scale above), the 6th and 7th scale degrees revert to their original form. The numeric scale formula is as follows:
1, 2, b3, 4, 5, b6, b7
Natural Minor Scale
Unlike the harmonic and melodic minor (ascending) scales, the natural minor scale does not have any alterations; in other words, the notes of the scale are purely determined by the key signature. It also happens to be the same scale as the descending form of the melodic minor scale. Hence, the natural minor scale also follows the same numeric formula:
1, 2, b3, 4, 5, b6, b7
Jazz Scales & Other Common Scales
Major Pentatonic Scale
The major pentatonic scale is made up five notes with the following numeric scale formula:
1, 2, 3, 5, 6
The major pentatonic scale is often taught as a beginner's jazz scale for improvisation over the blues. At the same time, it is a versatile scale that is often used in many other musical traditions, such as traditional Chinese music.
A little extra trivia about the major pentatonic scale: the notes of a major pentatonic scale can be reorganized into a stack of perfect fifth intervals starting from the key note. For example, the notes
