"Lucidity" is a song by Tame Impala, released as a single in 2010. It was recorded during the sessions for the Innerspeaker album in 2009, and released as the second single from that album. The single features artwork from Australian artist Leif Podhajsky, who also created the artwork for Innerspeaker and the follow-up Lonerism. "Lucidity" came in at number 74 in the Triple J Hottest 100 in 2010.

"Lucidity" was written by Kevin Parker in the key of A major in a 4/4 time signature.

The verses feature heavily rhythmic strumming of the chords E7sus4add9 and E major. The pre-chorus features a variation of the verse vocal melody played on a fuzz guitar in the A major scale four times, before the verse rhythm plays one more time.

The chorus then comes in with a key change to G major, and a B major, Dmaj7, A major, G major barre chord progression. After the chorus, it switches back to the key of A major and there is a short arpeggio from C major to D major chords to connect to the next verse.

The second verse is half the length of the first one, and a short guitar solo in the A major scale comes in on the words "float away".
