A computer system provides a user interface for selecting intervals on a touchscreen device. A user interface is generated with a plurality of interval elements each representing an interval within a sequence. Contact is detected on the screen by a user at a location corresponding to the interval element and associated with a selected interval. A plurality of adjustment elements are generated proximate to the selected interval, wherein the adjustment elements enable modification of a span of the selected interval and a position of the selected interval in the sequence. A selection of one or more adjustment elements is received. One or more from a group of the span and position of the selected interval are modified based on the selected one or more adjustment elements. Embodiments of the present invention further include a method and program product for providing a user interface for selecting intervals on a touchscreen device in substantially the same manner described above.
