Thematic transformation (also known as thematic metamorphosis or thematic development) is a musical technique in which a leitmotif, or theme, is developed by changing the theme by using permutation (transposition or modulation, inversion, and retrograde), augmentation, diminution, and fragmentation.
Musical technique may also be distinguished from music theory, in that performance is a practical matter, but study of music theory is often used to understand better and to improve techniques. Techniques such as intonation or timbre, articulation, and musical phrasing are nearly universal to all instruments.
