Hi this is Robert Estrin at VirtualSheetMusic.com and LivingPianos.com. We have a viewer question, "Why are there sometimes double stems on notes?" Have you ever seen that? It's really interesting. You might think, "This is crazy!" But there is a good reason. We're going to cover that today.

Well, if you're a singer or you play a monophonic instrument like a trumpet, clarinet, or flute, you virtually never see double stemmed notes. It's only in polyphonic writing. You see, the piano, for example, you have multiple parts, and sometimes you'll have two notes on two different parts that are playing the same note at the same time.

Just imagine for example, if there was a choir singing and the sopranos and the altos, their line, at one note, they had the same note. Instead of writing the note twice, if it was written on one staff, they would put a stem going up for the soprano and down for the alto on the same note.

Sometimes you'll even have double stems with two different rhythms. You'll have a half note and a quarter note on the same note. The note holds for one line and the next line is going on with faster notes while that note is continuing to hold. There's great complexity and counter point delineating distinct musical lines. To be able to play more than one on one instrument, like you do on the piano, on stringed instruments like violin and cello, and guitar, classical guitar, we all see these on a regular basis.

That solves the mystery for those of you wondering why there are double stems on notes. Thanks so much for joining me, Robert Estrin, here at LivingPianos.com and VirtualSheetMusic.com.

clip was ok. Show me more by demonstrating more about how eight notes are played in different timings.

Please let me know if there is a particular piece of music which you would like guidance on. We may produce a video just for you!

Dear Professor Estrin:

I am learning the violin, but I always watch your videos because I find valuable information in reference to music in general and I thank you for this.

In the case of the first two-quarter notes on the screen showed as an example, my question is, -Should I play the written note together with the same note one octave lower or higher?*. In another words, -How can I know which are the two notes that I am suppose to play at the same time in accordance with the written note?

Looking forward for your response, I remain cordially yours.

Patricia

*I am ruling out to go one octave higher from the written note plus one octave lower from the written note resulting in two octaves apart. I believe to play this with the violin will be perhaps impossible.

When you have counterpoint with 2 lines for example and the 2 lines share a note at one point, it should be played exactly at the octave written. Ideally you would play both notes simultaneously on 2 different strings if possible. (It depends upon context.)
