# AI Wiki - Music - Piano Scales ## Why Practise Scales on Piano A scale is the set of notes a key is built from ([[AI Wiki - Music - Major Scale]], [[AI Wiki - Music - Minor Scales]]). On piano, practising scales does four jobs at once: - **Key geography.** Each key has its own pattern of white and black keys (see [[AI Wiki - Music - Piano Keyboard Layout]]). Playing the scale is the fastest way to know which black keys belong to G, D or B♭. - **Thumb crossing.** Scales are the main drill for passing the thumb under and the fingers over, which every melody longer than five notes needs. - **Evenness.** Equal volume and timing across all fingers, including the weak 4 and 5. - **Theory in the hands.** Degrees, key signatures and chord roots become physical. ## Fingering Logic Three rules generate almost every scale fingering ([[AI Wiki - Music - Piano Fingering]]): 1. Fingers come in a group of three (1-2-3) and a group of four (1-2-3-4); the thumb passes under at the join. 2. The thumb avoids black keys. 3. **Each hand uses its 4th finger exactly once per octave.** Learn where the 4 goes and the rest follows. For C, D, E, G and A (major and minor), the right-hand 4 is on the 7th degree and the left-hand 4 on the 2nd degree. For most flat keys, the right-hand 4 is on B♭. ## Group 1: C, G, D, A, E Major The five guitar-friendly keys all use the same fingering: - **Right hand:** 1 2 3 1 2 3 4 5 (thumb under after 3). - **Left hand:** 5 4 3 2 1 3 2 1 (3 crosses over after the thumb). The fingers stay the same; only the black keys change (F♯ in G; F♯ C♯ in D; F♯ C♯ G♯ in A; F♯ C♯ G♯ D♯ in E). In E major the 2nd and 3rd fingers land on F♯ and G♯, the most natural shape on the keyboard. ```keyboard columns: 2 --- G major range: G4-G5 fingering: 1 2 3 1 2 3 4 5 title: G major, RH --- D major range: D4-D5 fingering: 1 2 3 1 2 3 4 5 title: D major, RH --- A major range: A4-A5 fingering: 1 2 3 1 2 3 4 5 title: A major, RH --- E major range: E4-E5 fingering: 1 2 3 1 2 3 4 5 title: E major, RH ``` ## Group 2: F and B Major The two white-key exceptions: - **F major, right hand:** 1 2 3 4 1 2 3 4. The 4 lands on B♭, so the thumb crosses under to C. Left hand: 5 4 3 2 1 3 2 1, as in group 1. - **B major, left hand:** 4 3 2 1 4 3 2 1. The 4 lands on F♯ and the thumb never touches a black key. Right hand: 1 2 3 1 2 3 4 5, as in group 1. ```keyboard columns: 2 --- F major range: F4-F5 fingering: 1 2 3 4 1 2 3 4 title: F major, RH --- B major range: B4-B5 fingering: 4 3 2 1 4 3 2 1 title: B major, LH ``` ## Group 3: Black-Key Major Scales Scales that start on a black key can't start on the thumb. In B♭, E♭, A♭ and D♭ the right thumb plays **C and F**; the left hand uses the same fingering, 3 2 1 4 3 2 1 3, in all four keys. G♭ (F♯) major is the odd one out. | Major scale | Right hand | Left hand | | --- | --- | --- | | C, G, D, A, E | 1 2 3 1 2 3 4 5 | 5 4 3 2 1 3 2 1 | | F | 1 2 3 4 1 2 3 4 | 5 4 3 2 1 3 2 1 | | B | 1 2 3 1 2 3 4 5 | 4 3 2 1 4 3 2 1 | | B♭ | 4 1 2 3 1 2 3 4 | 3 2 1 4 3 2 1 3 | | E♭ | 3 1 2 3 4 1 2 3 | 3 2 1 4 3 2 1 3 | | A♭ | 3 4 1 2 3 1 2 3 | 3 2 1 4 3 2 1 3 | | D♭ | 2 3 1 2 3 4 1 2 | 3 2 1 4 3 2 1 3 | | G♭ / F♯ | 2 3 4 1 2 3 1 2 | 4 3 2 1 3 2 1 4 | Fingering runs from the tonic up one octave. Black-key scales are often *easier* than white-key ones: the black keys sit under the long fingers and mark exactly where the thumb goes. ```keyboard columns: 2 --- Bb major range: Bb4-Bb5 fingering: 4 1 2 3 1 2 3 4 title: Bb major, RH (thumb on C and F) --- Eb major range: Eb4-Eb5 fingering: 3 1 2 3 4 1 2 3 title: Eb major, RH (thumb on F and C) ``` ## Minor Scales Every minor key has three forms ([[AI Wiki - Music - Minor Scales]]): natural, harmonic (raised 7th) and melodic (raised 6th and 7th going up, natural going down). For the white-key tonics A, E, D, G and C, all three forms keep the group-1 fingering, because the 4th-finger positions don't change. B minor and F minor follow B major and F major. | Minor scale (harmonic) | Right hand | Left hand | | --- | --- | --- | | A, E, D, G, C | 1 2 3 1 2 3 4 5 | 5 4 3 2 1 3 2 1 | | B | 1 2 3 1 2 3 4 5 | 4 3 2 1 4 3 2 1 | | F | 1 2 3 4 1 2 3 4 | 5 4 3 2 1 3 2 1 | | F♯ | 3 4 1 2 3 1 2 3 | 4 3 2 1 3 2 1 4 | | C♯ | 3 4 1 2 3 1 2 3 | 3 2 1 4 3 2 1 3 | | G♯ | 3 4 1 2 3 1 2 3 | 3 2 1 4 3 2 1 3 | A minor is the relative minor of C ([[AI Wiki - Music - Relative and Parallel Keys]]) and the guitarist's home key. Here is its harmonic form against the natural one: only G becomes G♯. ```keyboard A harmonic minor range: A4-A5 compare: natural minor title: A harmonic minor vs A natural minor ``` ```keyboard A minor range: A4-A5 fingering: 1 2 3 1 2 3 4 5 title: A minor, RH ``` ## A Practice Routine Ten minutes a day is enough if it's consistent: 1. **Pick the key of the week.** Follow the [[AI Wiki - Music - Circle of Fifths]]: C, G, D, A, E, then F, B♭, E♭, then the remaining black-key scales. Pair each major with its relative minor (C/Am, G/Em, D/Bm, A/F♯m, E/C♯m). 2. **Hands separately, one octave**, slowly (about 60 bpm, one note per click), saying the finger numbers aloud. Check the thumb crossing is silent and even. 3. **Two octaves**, hands separately, then **four octaves** once two are reliable. 4. **Contrary motion first.** Start both thumbs on the same C and move the hands apart: in contrary motion the fingering is a mirror image (both hands 1 2 3 1 2 3 4 5), so the crossings happen together. It's the easiest way into hands together. 5. **Parallel motion** an octave apart. The crossings now happen at different times, which is the real coordination test ([[AI Wiki - Music - Hand Independence]]). 6. **Rhythm variations.** Dotted rhythms (long-short, then short-long), accents every 3 or 4 notes, legato and staccato. Raise the [[AI Wiki - Music - Metronome and Speed Building|metronome]] by small steps only when it's clean at the current tempo. 7. **Add the arpeggio** of the same key ([[AI Wiki - Music - Arpeggios]]) and the I-IV-V chords in that key. For [[AI Wiki - Music - Chord Tones and Improvisation|improvising]], add the [[AI Wiki - Music - Pentatonic Scale]] of the same key once the major and minor scales feel familiar. ## Common Mistakes - Playing scales fast and uneven instead of slow and even. - "Thumb thump": the thumb arrives louder than the other fingers after the crossing. - Twisting the wrist or lifting the elbow on the crossing; the thumb should travel under the palm while the hand moves smoothly sideways. - Switching fingering between run-throughs. - Practising only the right hand; the left hand's crossings come at different points and need their own repetitions. - Using the key signature without knowing it: name the sharps or flats before starting ([[AI Wiki - Music - Keys and Key Signatures]]). ## Key Points - C, G, D, A, E major: RH 1 2 3 1 2 3 4 5, LH 5 4 3 2 1 3 2 1. - F major changes the right hand (1 2 3 4 1 2 3 4); B major changes the left hand (4 3 2 1 4 3 2 1). - B♭, E♭, A♭, D♭: right thumb on C and F; left hand 3 2 1 4 3 2 1 3. - Each hand uses its 4th finger once per octave; find it first. - Minor scales on white-key tonics use the major fingering. - Contrary motion is the easiest hands-together start; parallel motion is the real test. ## Open Questions - **Answered** ([[AI Wiki - Music - Modes of Melodic and Harmonic Minor|Modes of Melodic and Harmonic Minor]]): Which melodic minor scales need a different fingering going up and down? With the standard minor fingerings, three cases: F♯ and C♯ minor in the right hand going up (the thumb would land on D♯ or A♯; use 2 3 1 2 3 4 1 2) and G♯ minor in the left hand going down (the thumb would land on F♯); all other keys keep one fingering. - What tempo goal (bpm, notes per beat) is a sensible benchmark for an intermediate player? - Is a separate fingering for the pentatonic and [[AI Wiki - Music - Blues Scale|blues scales]] worth learning, or do players just adapt the major-scale fingering? ## References - Burt, University of Miami, "Fingering charts, piano scales": https://www.cs.miami.edu/home/burt/music/finger-charts.html (fourth-finger placement for every major and harmonic minor key) - PianoGroove, "Major Scale Fingerings & Technique": https://pianogroove.com/jazz-piano-lessons/major-scale-fingerings (white-key and black-key groups, exceptions F, B and G♭, crossing technique) - musictheory.net, "The Major Scale": https://musictheory.net/lessons/21 - musictheory.net, "The Minor Scales": https://musictheory.net/lessons/22 - Wikipedia, "Fingering (music)": https://en.wikipedia.org/wiki/Fingering_(music) ## Related - [[AI Wiki - Music - Major Scale]] - [[AI Wiki - Music - Minor Scales]] - [[AI Wiki - Music - Piano Fingering]] - [[AI Wiki - Music - Piano Keyboard Layout]] - [[AI Wiki - Music - Circle of Fifths]] - [[AI Wiki - Music - Keys and Key Signatures]] - [[AI Wiki - Music - Relative and Parallel Keys]] - [[AI Wiki - Music - Arpeggios]] - [[AI Wiki - Music - Pentatonic Scale]] - [[AI Wiki - Music - Hand Independence]] - [[AI Wiki - Music - Capo and Transposition]] - [[AI Wiki - Music - Relative and Perfect Pitch]] - [[AI Wiki - Music - Solfege and Singing]] - [[AI Wiki - Music - Piano Technique and Posture]] - [[AI Wiki - Music - Plateaus and Motivation]] - [[AI Wiki - Music - Practice Routines and Planning]] - [[AI Wiki - Music - Sight-Reading]] - [[AI Wiki - Music - Swing and Shuffle Feel]] - [[AI Wiki - Music - Warm-Ups and Technical Exercises]] - [[AI Wiki - Music - Modes of Melodic and Harmonic Minor]] - [[AI Wiki - Music - Digital Pianos and MIDI]] - [[AI Wiki - Music - Piano Tips and Tricks]]
