Minhag Telz is not to say Ledovid by either Mincha or Maariv
Minhag Telz is also not to say Ledovid on Shabbos ,Rosh Hashana and Yom Kippur
Minhag Telz is also not to say Ledovid after Yom Kippur
Amongst the many Gedolim
whose Minhag was not to
say לדוד ה' אורי from Rosh Chodesh Ellul till Simchas Torah was
the Vilna Gaon.
The Aderes* writes the reason
for not saying it, is because of
Tircha Detzibura.
Saying one Kapitel Tehillim
takes up too much time from the Tzibbur.
Perhaps we can explain the Aderes -Gaon:
There is no mention in Bavli,
Yerushalmi, Rishonim, Tur & Shulchan
Aruch etc. to say Ledovid Hashem (in Ellul)
The first to mention to say
it Betzibbur** is the Sefer Chemdas Hayomim***
&Sefer Shem Tov Katan which are based on Kabbala****.
The Gaon in general was
against adding new Tefillos. He tried to
stick to as much as possible to the original
Tefillos from the Anshei Knesses Hagedola.
A Shliach Tzibbur who
starts one minute late in a Minyan of 100
people, wasted
not one minute but100
minutes. (Tircha of 100 people times
1 minute)
Adding a Kapitel Tehillim
which takes to say only one minute can at
times
be considered taking 100
minutes.
This might explain why the
Gaon
didn't say it.
*הרב
אליהו דןד רבינוביץ תאומים
(he was a twin)
**The Sefer Shem Tov Katan
printed before the Chemdas
Hayomim
mentions only to say it ביחיד
.
***major controversy who the
author was.Some don't say
Ledovid Hashem Ori
because they
claim the source
is Nasan Ha'azasi
yms.
**** I believe the first
Halacha Sefer
to say it is the Mateh
Efraim
