be familiar with English. The chalkboard writing's transformation into a snake was included to surprise the audience and "end the song on a high note." In writing the song "Taare Zameen Par," lyricist Prasoon Joshi followed the theme of "however much you talk about children, it's not enough." Every line throughout the song describes children, and only one repeats: "Kho Naa Jaaye Yeh / Taare Zameen Par" ("Let us not lose these / Little stars on earth"). The song is mostly set to the annual day performance by the developmentally disabled children of Tulips School. Actual students from Tulips School and Saraswati Mandir participated, and were filmed over a period of five days. The sequence originally featured numerous dance performances, but was trimmed down when test audiences found it too long. A song accompanying the scene in which Ishaan's mother is watching home videos of her son was also cut, and replaced with background music after test audiences expressed their opposition to yet another song. Background music Timing and other aspects are usually planned when scoring a film, but Khan chose to take a more improvised approach. Instead of using a studio, he and the trio Shankar–Ehsaan–Loy recorded it at Khan's home in Panchgani, to clear their heads and not be in the mindset of the city. As they watched the film, Khan pointed out when he wanted music to begin and of what type. Ehsaan Noorani noted that this strategy allowed the score to have a "spontaneity to it." Different styles of background music were used to convey certain things. For example, a guitar is played when Ishaan is tense or upset, sometimes with discordant notes. The music of the opening scene—the recurring "Ishaan's Theme," which represents the character's peace of mind—overpowers the background noise to show that Ishaan is lost in his own world; the noise becomes louder after he snaps back to reality. But the scene in which Nikumbh explains dyslexia to Ishaan's family took the opposite approach. Silent at first, the music is slowly introduced as the father begins to understand his son's dilemma. The almost seven-minute long scene scarcely used any background music, to slow the pace and make it seem more realistic. Promotional material When filming part of the montage that details Ishaan's tutoring by Nikumbh, Khan immediately decided it would be the "key art of the film". He noted that "this one shot
