This simple, effective form was a favourite not only of Baroque composers but also of the Classical period composers who followed them. If you listen to symphonies by Mozart and Haydn you will often hear a lively, bright and fresh last movement that adds a new musical idea, or a new reworking of a previously heard one, somewhere between its middle and end.
This musical devise was very useful to classical composers, as it enabled them to keep a trick or two up their sleeves for later in their works, keeping their audiences (who were very knowledgeable and aware of the nuances of musical form) interested and attentive. Haydn was especially well-known for the musical jokes and surprises he would include in his symphonies, especially during their last movements.
The principle at work here is one of introducing new ideas into a pre-existing structure, and it is easily applicable to non-musical situations and problems.
Useful questions to ask when applying this principle are:
- What new, apparently unrelated ideas have we not considered so far when thinking about the issue or problem?
- What are we not seeing, appreciating or using and how can we start doing so?
- When was the last time we considered something new? (If it was some time ago do we need an injection of freshness? Do we need to bring in someone new or create some new roles and responsibilities, etc.?)
- Can we look at old ideas in new ways? Can we develop them in innovative ways?
Lastly, the Rondo Form gives us guidance about when new ideas are most likely to be needed and appreciated. This is somewhere between the middle and end of a task or project (or if a long project somewhere between the middle and end of its significant stages).
