 > [!NOTE]
 > An instance will play once, to loop the sound, you can use the **[SoundEffectInstance.IsLooped](xref:Microsoft.Xna.Framework.Audio.SoundEffectInstance.IsLooped)** property to set the sound to loop. Also note that the sound will not repeat until the sound has finished playing. You can utilise the **[SoundEffectInstance.State](xref:Microsoft.Xna.Framework.Audio.SoundEffectInstance.State)** property to check if the sound is playing, paused or stopped. Use the **[SoundEffectInstance.Stop](xref:Microsoft.Xna.Framework.Audio.SoundEffectInstance.Stop)** method to stop the sound.

 6. In the **[Game.Update](xref:Microsoft.Xna.Framework.Game.Update)** method, check if the **Space** key is pressed and adjust the pitch and volume of the sound effect accordingly. The pitch and volume values are adjusted by +0.1f each time the **Space key** is pressed. The pitch values are clamped to a minimum value of -1.0f and a maximum value of 1.0f, and the volume values are then clamped to a minimum value of 0f and a maximum value of 1.0f. This is done to ensure that the pitch and volume values are within  valid ranges.
