📌 CONCEPT: Fibonacci numbers in music composition refer to the use of a sequence of numbers where each note is a Fibonacci number, starting with note 1, to create a unique melody with aesthetic appeal.

📐 RULE / FORMULA: The Fibonacci sequence is a series of numbers in which each number is the sum of the two preceding numbers: 1, 1, 2, 3, 5, 8, 13, and so on.

💡 WORKED EXAMPLE: Suppose we want to create a melody using the first 8 Fibonacci numbers. The sequence would be: 1, 1, 2, 3, 5, 8, 13, 21. A possible melody could be a sequence of notes corresponding to these numbers, where each note has a specific duration or pitch.

⚠️ COMMON MISTAKE: Students often assume that a Fibonacci melody will sound pleasant or harmonious, but in reality, the actual sound depends on various factors such as note duration, pitch, and rhythm. A well-designed Fibonacci melody can be aesthetically pleasing, but it's not a guarantee.
