Psalm 32 is both a thanksgiving and a penitential hymn in which the worshippers thank God for forgiving their sins.  Psalm 32 is often associated with Psalm 51, but there is not much to sustain that claim, rather Psalm 32 is general in nature, and it is applicable to all confession and forgiveness. 

1-5 – Psalm 32 presents deep spiritual truth; a person is only blessed and happy when his sins are forgiven.  Forgiveness of sin and iniquity is God’s expression of kindness and mercy to his covenant people.  Only when we uncover and do not hide our iniquities, our sins, will God forgive the iniquity and blot it out.  

6-11 – This section opens with the word, therefore.  Therefore, this deep Biblical truth can be applied to everyone who repents and confesses his sin to God, while God may be found.  Do not be foolish and wait indefinitely to confess your sins.  The godly are not sinless, but they readily confess their sins.  There is a contrast presented between sorrows suffered by the wicked and the steadfast love of God that surrounds the godly person.
