Ongarello's harmonic approach is rooted in a deep understanding of jazz harmony and chord progressions. He emphasizes the importance of analyzing chord changes, identifying key harmonic moments, and developing a keen sense of ear-based musicianship. By internalizing the harmonic structures of jazz standards, guitarists can improvise with greater authority and creativity, crafting melodic lines that are both coherent and compelling.
One of Ongarello's key technical innovations is his use of the "three-finger system," which involves using the index, middle, and ring fingers to play chords and melodic lines. This approach allows for greater dexterity and flexibility, enabling guitarists to play complex harmonies and rapid-fire lines with precision and accuracy.
Ongarello's approach to jazz guitar technique emphasizes the development of a strong, flexible left hand, capable of navigating complex chord shapes and melodic lines with ease. He stresses the importance of proper hand positioning, finger independence, and a deep understanding of the fretboard's geography. By mastering these fundamental skills, guitarists can tackle even the most challenging jazz standards and improvisations with confidence.
One of Ongarello's signature harmonic techniques is his use of "chord substitution," which involves replacing chords with altered or extended chords to create richer, more complex harmonies. This approach allows guitarists to add depth and nuance to their playing, creating unexpected harmonic surprises that engage and delight listeners.
Ongarello is widely respected for his ability to communicate complex musical concepts through clear, concise language and a range of effective teaching tools. His pedagogical approach emphasizes the importance of ear-based learning, encouraging students to develop their ears and internalize musical concepts through a combination of listening, transcription, and practice.
