Steps to Ecstasy can be performed by either a Baroque original instruments orchestra or a modern orchestra (small or medium size).
A few points should be noted:
1) Notes in brackets are for Baroque instrument ranges. Any other notes outside of the Baroque range can be displaced by an octave.
2) If performed by a small ensemble, there is no need for double winds and/or 2 solo violins.
3) When the harpsichord is used disregard the dynamics.
