In music notation, tying notes generally indicates that two notes of the same pitch are to be played as a single sustained note. For example, if you have two quarter notes of the same pitch tied together, it means you hold the note for their combined duration (e.g., two quarter notes would equal a half note).
Ties cannot be used to connect notes of different pitches; instead, you would typically use different notation or symbols for that purpose. If you want to indicate a transition from one pitch to another, you would simply notate the two separate notes as they are.
If you mean in an extended or conceptual sense, such as in a polyrhythmic or complex compositional context (for example, in certain types of jazz or modern music), the term may be metaphorically used, but it wouldn't be a conventional use of the term "tie" in music notation.
In summary, ties are strictly for notes of the same pitch; different pitches would be written as separate notes.
