What to wear
Whilst most people consider classical performances to be a formal event, dress codes are not usually enforced. Especially in Singapore, the attire is usually smart casual.

What is NOT acceptable: singlets, tank tops (for men), shorts, slippers (for men)

Late seating
Most performances in Singapore will start on time (give and take a couple of minutes) unless otherwise stated. Patrons are encouraged to arrive at least 30 minutes before to give ample time to find their seats, browse a programme notes etc. Latecomers will only be admitted at suitable intervals ie: in between the pieces, sometimes in between movements or even at intermission for some performances. It is observed that in most venues around the world, latecomers will not be admitted at all until intermission (if there is no intermission, patrons will miss the performance altogether)

Concert program booklets
Most Esplanade presents performances comes with complimentary program books. However it is advised for patrons to take only one copy each (or share) so as to allow sufficient copies for everyone.

Interruption and distraction
Switch off all mobile phones and beeping devices prior to entering the auditorium. Noise of any kind ie: talking, coughing, sweet wrappers (there should not be any eating in the hall anyways), plastic bags can be distracting to the performers and audiences. Unauthorized filming, audio recording and photography are strictly prohibited in the auditorium. If you need to cough or clear your throats, do so when the music or sound is at its highest level (such as when the music picks up).

When to applaud
Just before the concert begins, applause is given to the concertmaster as he steps on stage. Further applause is given to the conductor and soloist (if any) as they enter. There should NOT be any more applause until the end of each piece of music. Sometimes longer pieces can have several sections or movements as they are usually referred as which are separated by brief silent pauses. Do not applause during these breaks as you may distract the concentration of the conductor/soloist/musicians/audiences.

If unsure when to applaud, check the program and count the movements in each pieces. (An example of a piece with 3 movements is appended below) Or simply follow the applause of the audience in the auditorium or when the conductor/soloist takes a bow.

Wolfgang Amadeus Mozart Piano concerto No. 12 in A Major, K.414. 24’00 (duration)
Movement 1 – Allegro
Movement 2 – Andante
Movement 3 – Allegretto
Applaud

At the end of the concert, the conductor and/or soloist will return for curtain call/s depending on the level of applause. Sometimes shouts of “Bravo”, “Encore” can be heard from the audience. Please do not leave the auditorium until all applause have ceased. This applies to dance performances ie: ballet as well as musical theatre.
