The concept of harmony is most closely related to the interaction of different notes and chords in music. Harmony refers to the simultaneous sounding of different pitches to create a pleasing sound. While rhythm and melody are also important elements in music, harmony specifically deals with the vertical aspect of music, focusing on how notes and chords interact with each other. Therefore, harmony belongs more to the realm of harmony itself. **

Rhythm refers to the pattern of sounds and silences in music, creating a sense of movement and pulse. Melody is the sequence of musical notes that are perceived as a single entity, often the most recognizable and memorable part of a song. Harmony involves the combination of different musical notes played or sung simultaneously, creating a pleasing sound. While rhythm provides the framework for the timing of music, melody is the main tune, and harmony adds depth and richness to the overall sound. **

Both types of skates have their own unique advantages, so it's important to consider your skating style and preferences before making a decision. **
