The video opens by addressing a common problem among musicians: fearing a difficult passage in a piece. It questions the universally recommended strategy of starting slow and gradually increasing tempo, which seems logical but overlooks how the brain functions, leading to inefficiencies and wasted time in practice.
When playing very slowly, a different part of the brain (the frontal lobe) is active, allowing for precise control and analysis. When playing at a fast tempo, the motor cortex takes over, managing automated movements. The video explains that practicing at intermediate speeds doesn't effectively train either region, resulting in motor learning that isn't transferable to the final tempo.
A deeper dive into brain function reveals that the frontal lobe is active during slow, controlled playing, while the motor cortex handles fast, automated movements. The problem with gradual tempo increase is spending too much time in an 'intermediate zone' where neither brain region is optimally engaged, making the learning process less effective for the desired final speed.
The gradual tempo increase strategy can be acceptable if the musician reaches the final tempo halfway through their preparation period, ensuring more practice time at the target speed. However, the video suggests that this often isn't practical or efficient, leading to a significant loss of practice time that could be better utilized.
The first alternative strategy is 'accumulation practice.' This involves playing the first two notes of a difficult passage at the final tempo, achieving success several times, then adding one note at a time (three notes, then four, and so on) while maintaining the final tempo. A variation suggests starting from the end of the passage and working backward.
This strategy, translated as 'fill and refill,' involves playing only the first and last notes of the difficult passage at the final tempo, with correct articulation and dynamics. Then, gradually reintroduce the missing notes into their rhythmic positions, leaving silences where notes are not yet reintegrated. The progression is in the number of notes played, not the tempo.
The preferred strategy is the 'point d'orgue' (fermata) method. Break the difficult passage into small groups of notes (e.g., two notes), play them at the final tempo, and place a fermata on the last note of each group. This allows for resetting muscle tension, posture, and breathing. Gradually increase the number of notes in each group (three, four, etc.) until the entire passage can be played with ease at the final tempo.
The video concludes with an important warning: these strategies are specifically for difficult passages that need to be played at a high, specific tempo, requiring automation of movements. They are not intended for slow pieces, technical exercises, or scales, which musicians should be able to play at various speeds.
