Warm-Up & Review (10 minutes)

Dynamic Scale Warm-Up (4 minutes)

Play C major scale, 2 octaves, HT, at 72 BPM — but with dynamic shape:

Ascending: Start pp (as soft as possible). Crescendo through the scale. Arrive at the top note ff (as loud as possible).
Descending: Start ff. Diminuendo through the scale. Arrive at the bottom note pp.

This is a hairpin dynamic: pp → ff → pp across the full scale. Do this 3 times. Feel the full range of your touch response.

Now play A harmonic minor with the same dynamic hairpin. 2 times.

Pedaling Review (3 minutes)

Play the “Imagine” introduction (measures 1-4), both hands, with legato pedaling. Is the pedal clean? No mud?

Arpeggio Review (3 minutes)

Play C, G, Am arpeggios, 1 octave, HT, at 60 BPM. Play them legato (connected, smooth) the first time, then staccato (short, bouncy) the second time. These are the two articulations you will study today.

Theory / Harmony (10 minutes)

The Full Dynamic Range

In the beginner course, you learned three dynamics: p (soft), mf (medium), and f (loud). Now you expand to the full range:

Marking	Name	Meaning	Touch
pp	Pianissimo	Very soft	Barely touching the keys — the lightest possible touch that still produces sound
p	Piano	Soft	Light touch, gentle
mp	Mezzo-piano	Moderately soft	Slightly louder than p — the “speaking voice” of piano
mf	Mezzo-forte	Moderately loud	The default — conversational volume
f	Forte	Loud	Firm touch, projecting
ff	Fortissimo	Very loud	Strong, powerful — using arm weight, not just finger force

Demonstration: Play Middle C at each dynamic level, from pp to ff. Can you produce 6 distinctly different volumes? On an acoustic piano, this is about touch weight. On your CT-X9000IN with touch response, it is about how fast and firmly your finger strikes the key.

Special Dynamic Markings

Sforzando (sfz): A sudden, forceful accent on a single note or chord. You are playing at p or mf, then suddenly one note is f or ff, then immediately back to the previous dynamic. It is like a shout in the middle of a whisper.

Play this: C(mf) D(mf) E(sfz!) F(mf) G(mf). The E should jump out dramatically.

Crescendo (cresc.): Gradually getting louder. Written as a hairpin: < Diminuendo (dim.) or Decrescendo (decresc.): Gradually getting softer. Written as a hairpin: >

You learned these in the beginner course but now you apply them with more precision and range.

Four Articulation Types

Marking	Name	Symbol	How to Play	Sound
Staccato	Detached	Dot above/below note	Quick release — key press is short	Short, bouncy, crisp
Legato	Connected	Slur line (curved)	Hold each note until the next begins	Smooth, singing, flowing
Accent	Emphasised	> above note	Strike more firmly than surrounding notes	A note that “pops”
Tenuto	Held	Short line above note	Hold for full value, perhaps slightly longer	Sustained, weighted

Demonstration on C-D-E-F-G (RH):

Staccato: C. D. E. F. G. — each note is short, separated by silence
Legato: CDEFG — each note connects seamlessly to the next
Accented: C D E F G — the E punches out
Tenuto: C- D- E- F- G- — each note is held to its full value with weight

Musical Phrasing

A phrase in music is like a sentence in language. It has a beginning, a middle (often a peak), and an end. Just as a speaker breathes between sentences, a musician shapes phrases with dynamics and tiny pauses.

The phrasing arch: Most phrases follow a natural arch — they start softly, grow toward a peak (usually the highest note), then taper off. This is the same pattern as human breathing and speaking.

Play C-D-E-F-G-F-E-D-C with this phrasing:

C(p) D(mp) E(mf) F(f) G(mf) F(mp) E(p) D(pp) C(pp)

The melody swells to G and then fades back. This is a phrase arch. It turns a sequence of notes into a musical statement.

Rubato

Rubato means “stolen time.” You slightly speed up in some places and slow down in others, bending the strict metronome timing to create expressiveness. Think of it as musical breathing — stretching and compressing time.

Rubato is central to Romantic-era music (Chopin, Schumann, Liszt). You do not use rubato in Bach or in strict pop songs. You use it when the music calls for emotional flexibility.

Rule of rubato: Whatever time you “steal” from one place, you must “give back” in another. If you slow down for an emotional moment, you speed up slightly after to catch up. The overall tempo remains roughly the same — the flexibility is within phrases, not across the entire piece.

Technique (15 minutes)

Dynamic Control Exercise (5 minutes)

Play a C major chord (C-E-G, RH) at each dynamic level. Hold for 4 beats each:

pp — p — mp — mf — f — ff

Then reverse: ff — f — mf — mp — p — pp

Can you produce 6 clearly different volumes? If pp and p sound the same, you need a lighter touch for pp. If f and ff sound the same, you need more arm weight for ff.

Technique for ff: Do not slam the keys. Instead, use arm weight — let the weight of your forearm drop into the keys through relaxed fingers. This produces a powerful, resonant sound without harshness.

Technique for pp: Use only fingertip contact, with minimal arm weight. Imagine touching a butterfly — the lightest possible touch that still depresses the key.

Articulation Drill (5 minutes)

Play the G major scale, 1 octave, RH, at 80 BPM, in four different articulations:

All staccato: G. A. B. C. D. E. F#. G. — short, crisp, bouncing off the keys
All legato: GABCDEF#~G — connected, smooth, each note overlapping slightly with the next
Accented first beat of each pair: G A B C D E F# G
Tenuto on every note: G- A- B- C- D- E- F#- G- — each note held for its full value with gentle weight

Repeat with LH in the same key.

Phrasing Exercise (5 minutes)

Play this 8-note phrase in C major, RH:

C(1) D(2) E(3) F(4) G(5) F(4) E(3) D(2)

Now add phrasing:

Start p
Crescendo to the peak (G on beat 5)
Diminuendo back to p by the end
Add a tiny breath (lift) between D(beat 8) and the start of the next phrase

Play this phrase 4 times with this dynamic shape. It should sound like someone singing — rising, peaking, falling, breathing.

Now try the same phrase with rubato:

Slightly slow down approaching the peak (G)
Slightly speed up as you descend
The phrase breathes, stretches, and contracts

Repertoire / Genre (25 minutes)

Chopin “Waltz in A minor” B.150 — Simplified Arrangement

This posthumous waltz by Chopin is a perfect showcase for dynamics and articulation. It alternates between tender, singing phrases and more energetic, dance-like sections. The waltz rhythm (3/4) with its “oom-pah-pah” LH pattern is the foundation.

Tempo: 100 BPM (Allegretto — moderate waltz tempo, start at 80) | Time Signature: 3/4 | Key: A minor

Right Hand — A Section (Main Theme):

Measure 1: E(3) — dotted quarter | D#(2) E(3) — two eighth notes | (dotted quarter + eighth + eighth)

Measure 2: F(4) quarter | E(3) quarter | D(2) quarter |

Measure 3: C(1) quarter | D(2) quarter | E(3) quarter |

Measure 4: B(2) — dotted half (hold 3 beats) |

Measure 5: C(1) — dotted quarter | B(2) C(1) — two eighths |

Measure 6: D(2) quarter | C(1) quarter | B(2) quarter |

Measure 7: A(1) quarter | B(2) quarter | C(3) quarter |

Measure 8: B(2) — dotted half (hold 3 beats) |

Measure 9: E(3) — dotted quarter | D#(2) E(3) — two eighths |

Measure 10: F(4) quarter | E(3) quarter | D(2) quarter |

Measure 11: C(1) eighth D(2) eighth | E(3) quarter | A(5) quarter |

Measure 12: G#(4) quarter | A(5) quarter | rest quarter |

Measure 13: B(3) eighth C(4) eighth | D(4) quarter | F(5) quarter |

Measure 14: E(4) quarter | D(3) quarter | C(2) quarter |

Measure 15: B(1) quarter | C(2) eighth B(1) eighth | A(1) eighth G#(2) eighth |

Measure 16: A(1) — dotted half (hold) — final |

Left Hand — Waltz Pattern:

The LH plays the classic waltz “oom-pah-pah” pattern:

Measure 1 (Am): A(5) — bass note | E(2) A(1) — chord on beats 2-3

Measure 2 (Dm): D(5) | F(3) A(1)

Measure 3 (Am): A(5) | E(2) A(1)

Measure 4 (E7): E(5) | G#(3) B(1)

Measure 5 (Am): A(5) | E(2) A(1)

Measure 6 (Dm): D(5) | F(3) A(1)

Measure 7 (Am): A(5) | E(2) A(1)

Measure 8 (E7): E(5) | G#(3) B(1)

Measure 9 (Am): A(5) | E(2) A(1)

Measure 10 (Dm): D(5) | F(3) A(1)

Measure 11 (Am): A(5) | C(3) E(1)

Measure 12 (E7): E(5) | G#(3) B(1)

Measure 13 (G): G(5) | B(3) D(1)

Measure 14 (C): C(5) | E(3) G(1)

Measure 15 (E7): E(5) | G#(3) B(1)

Measure 16 (Am): A(5) | E(2) A(1) — final Am chord

Dynamic Markings for This Performance:

Measures	Dynamic	Expression
1-4	p (soft, tender)	The opening theme is intimate — like a private conversation
5-8	pp (even softer)	The melody descends — pull back further
9-12	mf (growing)	The return of the theme, now with more confidence
13-14	f (bold)	The climax — the melody reaches its highest point
15-16	dim. to p	Fading away — the waltz ends gently

Articulation:

RH melody: legato throughout. Connect each note to the next.
LH waltz pattern: bass note slightly accented (the “oom”), chord notes lighter (the “pah-pah”)
Measure 1, beat 1: slight accent on the opening E — it announces the theme
Measure 13-14: stronger accent on the high notes — this is the emotional peak
Final note (A, measure 16): tenuto — hold it slightly longer than written, letting it ring

Rubato suggestions:

Slow down slightly at the end of measure 4 (before the second phrase begins)
Slow down at measure 12 (before the climax)
Slow down at measures 15-16 (the ending)
Speed up slightly through measures 9-10 (building energy toward the climax)

Both Hands Together — Practice Strategy:

LH waltz pattern alone, all 16 measures — The “oom-pah-pah” must be automatic. Play at 80 BPM. The bass note (beat 1) is slightly louder than the chord (beats 2-3).
RH melody alone with dynamics — Follow the dynamic markings above. Shape the phrases.
Both hands, measures 1-4 — Very slowly at 60 BPM. The melody floats above the waltz. 4 times.
Both hands, measures 5-8 — 4 times.
Both hands, measures 9-12 — Begin adding the crescendo.
Both hands, measures 13-16 — The climax and ending. 4 times.
Full piece at 80 BPM with dynamics and legato pedaling (change pedal each measure).
Target: 100 BPM with full expression — dynamics, articulation, pedal, and rubato.

Creative / Ear Training (10 minutes)

Dynamic Matching by Ear

Exercise 1: Dynamic Levels (4 minutes)

Play the same C major chord at different dynamics. Have someone tell you a dynamic level (pp, p, mp, mf, f, ff) — or say it to yourself — and play the chord at that level.

Then reverse: play a chord at a random dynamic level and identify what level it was. Was it p or pp? f or ff? Calibrate your ear and your touch.

Exercise 2: Phrase Shaping (3 minutes)

Play this phrase at mf throughout: C D E F G F E D C — flat, no shape.

Now play it with phrase shaping: p → mf → f at peak → mf → p — beautiful, musical.

The difference is dramatic. Same notes, same rhythm, but phrase shaping turns a scale fragment into a musical statement.

Try creating your own 8-note phrase and shape it with dynamics.

Exercise 3: Articulation by Ear (3 minutes)

Play the first 4 measures of the Chopin Waltz melody:

First time: all staccato (short, choppy)
Second time: all legato (smooth, connected)
Third time: legato melody with staccato LH

Which sounds best? The third option matches Chopin’s style — a singing, connected melody over a crisp, dance-like bass.

Common Mistakes to Watch For

Playing everything at mf: The most common expressive mistake. If everything is the same volume, nothing has shape. Force yourself to play pp — uncomfortably soft — and ff — uncomfortably loud. The contrast is what creates expression.
Mechanical rubato: Rubato should feel natural, like breathing. If you are counting “slow down NOW, speed up NOW,” it will sound artificial. Let the music guide you. Slow down where it feels emotional, speed up where it feels energetic.
LH too loud in the waltz: The waltz LH pattern (oom-pah-pah) should be pp to p — quiet and supportive. If your LH is as loud as your RH, the melody drowns. Practice the LH alone at pp.

CT-X9000IN Tips

Touch Response Sensitivity for Dynamic Control

Your CT-X9000IN’s touch response directly affects your ability to produce different dynamics. For this session, optimise it:

Accessing touch response settings:

Press FUNCTION button
Navigate to Touch Response (may be listed as “Touch” or “Velocity Sensitivity”)
Try these settings:

Setting	Effect	Best For
Light	Even a gentle touch produces moderate volume	Practicing pp passages
Normal	Standard response	General playing
Heavy	Requires firm touch for loud sound	Practicing ff and dynamic range

For this session: Set to Normal. This gives you the widest usable dynamic range.

Dynamic range test: With Normal sensitivity, play a key as softly as possible — can you still hear it? Now play as firmly as possible — does it feel dramatically louder? If the difference feels small, try Heavy sensitivity for a wider range.

After the session: Return to Normal for your regular practice. But revisit Heavy sensitivity occasionally — it strengthens your fingers and expands your dynamic control.
