In heaven, worship is characterised by adoration. These are the features of our worship in heaven:

Praise. We praise the Lord for Who He is and for what He has done. Angels and saints will praise Him (Rev 5:11–14)
Thanksgiving (Rev 11:17–18). We will thank God because we will be so filled with eternal gratitude.
Singing. Heaven will be filled with music and song (Rev 5:9). We will sing a new song. The word “new” here is “new” in terms of quality. We live in the blessings of God’s presence enjoying the Paradise He prepared for us.
