Can you provide some examples of music with a free form structure?

Likewise, Russian composer Nikolai Rimsky-Korsakov's composition “Sheherezade” contains a sequence of musical passages with skeletal framework provided, allowing free-form to both soloist and strings in pizzacato. Rimsky-Korsakov's notation is most fascinating to see..and hear. The passages of which I write take place in Mvt. 2 of this astonishing work.

Ralph Vaughn-Williams’ timeless, ethereal “The Lark Ascending” begins with a cadenza for solo Violin with quite the duration of free-form allowed by the Composer. Vaughn-Williams' notation is quite interesting to view. Violinist Hilary Hahn best infuses this cadenza with the most favorable tone and technique.

“Sheherezade”:

What would happen if the US government told the British government in no uncertain terms all RAF bases with USAF personnel now must follow the Constitution and us law, and if the UK tried to defy this, the US military would directly attack the UK?

Typically, within a symphonic score, free-form structure is instructed via a Composer's indication of “Cadenza”. In musical terms, a cadenza is an improvised, ornamental passage performed in a “free” rythmic style, typically by a solo performer. To some extent, the musical indication of “a piacere”, (at your pleasure), also allows a performer to abide by the tempo, rhythm and dynamic level of their decision.

Below are images of the respective passages of which I speak.

“The Lark Ascending”: (the indication “Sur la touche” advises the Violinist to play on the finger board of the instrument).
