To use this meditation timer, set the duration by either typing the minutes in the duration window or moving the timer clock hand with your mouse. By clicking on the musical notes you can choose music to play any time you want. Set the timer to time any event and have the music in the background. You may also paste any URL with music to the left of the music notes. You must select Begin after you make your music selection in order to hear the music. I have provided a varied assortment of music and/or voice recordings for listening, meditating or exercising. The clock displays the current time of your computer. This timer is free from poodwaddle.com - I am grateful.
