Gabriele introduces himself as a guitarist and physiotherapist, explaining how his scientific background has changed his approach to the instrument. The lesson introduces the concept of dynamic posture: not a rigid cage, but an adaptive system that supports the musical gesture. The different guitar-holding positions are illustrated — left leg, right leg, support devices — along with their practical advantages.

The focus shifts to the left hand and the compensatory mechanisms essential for correct work on the fretboard. Antero-posterior and lateral-lateral balancing movements are introduced, allowing the wrist to remain straight during position changes. The functional use of the thumb in barré chords, the role of diagonals and the risks of accumulated tension complete a lesson rich in technical and preventive implications.

We continue the in-depth study of balancing movements, focusing on lateral-lateral ones.

The lesson covers the free stroke and rest stroke of the right hand, starting from the principle of the natural elasticity of the fingers. It is clarified that the difference between the two strokes is not one of volume but of timbre, weight and tonal quality, and that both, after contact with the string, require an immediate release of the muscular impulse with the finger returning instantly to its natural state of rest. The double rest stroke is also introduced, along with the role of the nail attack angle on the string for managing timbral variations even without lateral shifts across the strings.

A lesson dedicated entirely to nail care and shaping — the physical point of contact between the guitarist and the strings. The correct files to use are illustrated — no cardboard ones, at least three progressive grits — along with the filing technique on all three surfaces of the nail: underside, front and top. It is explained why the shape should never be pointed or have waves or sharp edges, and how to correctly check the length by looking at the hand with the palm facing towards you.

Curciotti explores ascending and descending slurs in depth, reiterating the need to eliminate residual tension after each movement. The key principle is that the most important finger in a descending slur is not the one that moves, but the one holding the string in place. Vibrato is also introduced, explained as a movement originating from the elbow or wrist — never from the finger — and as a tool for muscular relaxation.

The lesson reveals the musical heritage hidden in guitar methods, often used only as mechanical exercises. Through studies by Sagreras, Giuliani and a piece by Signorile, Curciotti demonstrates how portamentos, vibratos, timbres and phrasing transform any exercise into authentic music. The practical goal is to develop, from the very beginning, a conscious musical thinking — even in the most elementary pieces.

Vibrato is explored as an expressive tool but also as a muscle recovery technique. A correct vibrato — originating from the wrist or elbow with the thumb detached — also serves as a diagnostic test: if the hand is well positioned, vibrato comes naturally; if it is tense, it becomes almost impossible. The lesson illustrates types and intensities of vibrato applied to the Largo from Paganini's Gran Sonata.

Through Fernando Sor's Study No. 5, the lesson teaches how to sing the music before playing it, in order to build an authentic interpretive idea. The concept of the upbeat as the engine of phrasing is introduced, as opposed to mechanical downbeat accenting. A harmonic analysis of the piece — from the degrees of B minor to the secondary dominant tensions — shows how understanding harmony supports both memory and interpretation.

The metronome is significantly reassessed in its too often excessive, if not compulsive, use: useful during rhythmic analysis or tempo control, it becomes counterproductive when systematically applied during the interpretive study phase. Building rigidly metronomic motor patterns makes it difficult to later introduce rallentandos, breathing and dynamics (phrasing and agogics). Curciotti proposes a selective and conscious use of the tool, thinking in terms of phrases or periods rather than individual bars.

Tonal layers in polyphonic music are the central theme, illustrated through the Canzone di Orfeo. Differentiating melody, bass, harmony and inner voices creates a three-dimensionality of sound that makes the performance both intelligible and engaging for the listener. Curciotti demonstrates practically how to bring out diminished chords, emphasise certain bass notes and manage dynamic levels without flattening the result.

Fingering is described as a choreography of the fingers: not a mechanical solution but the bridge between musical thought and its realisation on the fretboard. Through a prelude by Bach, Curciotti shows how bell-like tones, false barré, finger substitution and pivot fingers allow for fluidity, legato and timbral variety. A fingering built around the musical idea — not around convenience — is the master path.

Tremolo technique is analysed in detail, starting from the celebrated Recuerdos de la Alhambra. The hand must remain compact, the thumb must move with precision and control, while the distal phalanges of the index, middle and ring fingers must stay relaxed to prevent the fingers from "gripping" the string. Specific exercises are proposed: inverted tremolo, rest-stroke tremolo, stopping the bass note, varying the position on the fretboard to adapt to different string tensions.

The concluding lesson gathers the threads of the entire course and reminds us that the end of the course is, in reality, the beginning of independent study. Curciotti reiterates the importance of never settling for approximate results, of working through sections with an incremental method and of testing technical and interpretive choices by progressively increasing the tempo. A final invitation to cultivate courage, lightness in the face of mistakes and love for music.
