Dave's Tip of the Day: Beginner Tips #9 - Decay
Now that you're focusing on tremolo for those long-held notes at the end of phrases, also decay the volume. Start that last note at the volume you played the previous notes in the phrase and then decay the volume over the length of the notated rhythm of that note until it disappears. It's rare that a final note of a phrase just stops... it decays until it dispersers into the mix of the band. This makes for a MUCH more musical phrase ending and is a common error comment to beginner, intermediate and some advanced student submissions on BluesHarmonica.com
